+Known issues :
+       * Please read the associated RELEASE-NOTES file !!!
+       * This source release intended for upstream kernel releases only!
+
+Changes from 20050323 to 20050413
+
+       * Changed version number to 8.0.28
+       * Fixed build warning for 2.6.12-rc2 kernels: mempool_alloc now
+         requires a function which takes an unsigned int for gfp_flags.
+       * Removed pci dma sync calls to coherent/consistent pci memory.
+       * Merged patch from Christoph Hellwig <hch@lst.de>: split helpers
+         for fabric and nport logins out of lpfc_cmpl_els_flogi.
+       * Removed sysfs attributes that are used to dump the various
+         discovery lists.
+       * Fix for issue where not all luns are seen.  Search all lists
+         other than unmap list in lpfc_find_target().  Otherwise INQUIRY
+         to luns on nodes in NPR or other relevant states (PLOGI,
+         PRLI...) are errored back and scan() terminates.
+       * Removed FC_TRANSPORT_PATCHESxxx defines.  They're in 2.6.12-rc1.
+       * Compare return value of lpfc_scsi_tgt_reset against SCSI
+         midlayer codes SUCCESS/FAILED which that function returns rather
+         than SLI return code.
+       * Removed extraneous calls to lpfc_sli_next_iotag which should
+         only be called from lpfc_sli_submit_iocb.  Also make
+         lpfc_sli_next_iotag static.
+       * Added PCI ID for LP10000-S.
+       * Changes in lpfc_abort_handler(): Return SUCCESS if we did not
+         find command in both TX and TX completion queues.  Return ERROR
+         if we timed out waiting for command to complete after abort was
+         issued.
+       * Zero-out response sense length in lpfc_scsi_prep_cmnd to prevent
+         interpretation of stale sense length when the command completes
+         - was causing spurious 0710 messages.
+       * Moved clearing of host_scribble inside host_lock in IO
+         completion path.
+       * Fixed a bunch of mixed tab/space indentation.
+       * Allow hex format numbers in sysfs attribute setting.  Fix
+         application hang when invalid numbers are used in sysfs
+         settings.
+       * Removed extra iotag allocation by lpfc_abort_handler.
+       * Clear host_scribble in the scsi_cmnd structure when failing in
+         queuecommand.
+       * Changed logic at top of lpfc_abort_handler so that if the
+         command's host_scibble field is NULL, return SUCCESS because the
+         driver has already returned the command to the midlayer.
+
+Changes from 20050308 to 20050323
+
+       * Changed version number to 8.0.27
+       * Changed a few lines from patch submitted by Christoph Hellwig
+         (3/19). MAILBOX_WSIZE * (uint32_t) is replaced with an
+         equivalent MAILBOX_CMDSIZE macro.
+       * Merged patch from Christoph Hellwig (3/19): some misc patches
+         against the latest drivers:
+         - stop using volatile.  if you need special ordering use memory
+           barriers but that doesn't seem to be the case here
+         - switch lpfc_sli_pcimem_bcopy to take void * arguments.
+         - remove typecast for constants - a U postfix marks them
+           unsigned int in C
+         - add a MAILBOX_CMD_SIZE macro, as most users of
+           MAILBOX_CMD_WSIZE didn't really want the word count
+         - kill struct lpfc_scsi_dma_buf and embedded the two members
+           directly in struct lpfc_scsi_buf
+         - don't call dma_sync function on allocations from
+           pci_pool_alloc - it's only for streaming mappings (pci_map_*)
+       * Merged patch from Christoph Hellwig (3/19) - nlp_failMask isn't
+         ever used by the driver, just reported to userspace (and that in
+         a multi-value file which is against the sysfs guidelines).
+       * Change pci_module_init to pci_register_module() with appropriate
+         ifdefs.
+       * Added #include <linux/dma-mapping.h> as required by the DMA
+         32bit and 64bit defines on some archs.
+       * Merged patch from Christoph Hellwig (03/19) - fix initialization
+         order - scsi_add_host must happen last from scsi POV. Also some
+         minor style/comment fixups.
+       * Fixed use of TRANSPORT_PATCHES_V2 by changing to
+         FC_TRANSPORT_PATCHES_V2.
+
+Changes from 20050223 to 20050308
+
+       * Changed version number to 8.0.26
+       * Revise TRANSPORT_PATCHES_V2 so that lpfc_target is removed and
+         rport data is used instead. Removed device_queue_hash[].
+       * Changed RW attributes of scan_down, max_luns and fcp_bind_method
+         to R only.
+       * Fixed RSCN handling during initial link initialization.
+       * Fixed issue with receiving PLOGI handling when node is on NPR
+         list and marked for ADISC.
+       * Fixed RSCN timeout issues.
+       * Reduced severity of "SCSI layer issued abort device" message to
+         KERN_WARNING.
+       * Feedback from Christoph Hellwig (on 2/5) - In the LPFC_EVT_SCAN
+         case the caller already has the target ID handly, so pass that
+         one in evt_arg1.
+       * Fix compile warning/resultant panic in
+         lpfc_register_remote_port().
+
+Changes from 20050215 to 20050223
+
+       * Changed version number to 8.0.25
+       * Add appropriate comments to lpfc_sli.c.
+       * Use DMA_64BIT_MASK and DMA_32BIT_MASK defines instead of
+         0xffffffffffffffffULL & 0xffffffffULL respectively.  Use pci
+         equivalents instead of dma_set_mask and also modify condition
+         clause to actually exit on error condition.
+       * Restart els timeout handler only if txcmplq_cnt. On submission,
+         mod_timer the els_tmofunc.  This prevents the worker thread from
+         waking up the els_tmo handler un-necessarily.  The thread was
+         being woken up even when there were no pending els commands.
+       * Added new typedefs for abort and reset functions.
+       * Collapsed lpfc_sli_abort_iocb_xxx into a single function.
+       * Collapsed lpfc_sli_sum_iocb_xxx into a single function.
+       * Removed TXQ from all abort and reset handlers since it is never
+         used.
+       * Fixed Oops panic in 8.0.23 (reported on SourceForge).  The
+         driver was not handling LPFC_IO_POLL cases correctly in
+         fast_ring_event and was setting the tgt_reset timeout to 0 in
+         lpfc_reset_bus_handler.  This 0 timeout would not allow the FW
+         to timeout ABTS's on bad targets and allow the driver to have an
+         iocb on two lists.  Also split the lpfc_sli_ringtxcmpl_get
+         function into two routines to match the fast and slow completion
+         semantics - ELS completions worked for the wrong reasons.  Also
+         provided new log message number - had two 0326 entries.
+       * Removed unused #define LPFC_SCSI_INITIAL_BPL_SIZE.
+       * Removed unused struct lpfc_node_farp_pend definition.
+       * Removed unused #define LPFC_SLIM2_PAGE_AREA.
+       * Changed zeros used as pointers to NULL.
+       * Removed unneeded braces around single line in lpfc_do_work.
+       * Close humongous memory leak in lpfc_sli.c - driver was losing 13
+         iocbq structures per LIP.
+       * Removed last of GFP_ATOMIC allocations.
+       * Locks are not taken outside of nportdisc, hbadisc, els and most
+         of the init, sli, mbox and ct groups of functions
+       * Fix comment for lpfc_sli_iocb_cmd_type to fit within 80 columns.
+       * Replaced wait_event() with wait_event_interruptible().
+         wait_event() puts the woker thread in an UNINTERRUPTIBLE state
+         causing it to figure in load average calculations. Also add a
+         BUG_ON to the ret code of wait_event_interruptible() since the
+         premise is that the worker thread is signal-immune.
+
+Changes from 20050208 to 20050215
+
+       * Changed version number to 8.0.24
+       * Fixed a memory leak of iocbq structure.  For ELS solicited iocbs
+         sli layer now frees the response iocbs after processing it.
+       * Closed large memory leak -- we were losing 13 iocbq structures
+         per LIP.
+       * Changing EIO and ENOMEM to -EIO and -ENOMEM respectively.
+       * Cleanup of lpfc_sli_iocb_cmd_type array and typing of iocb type.
+       * Implemented Christoph Hellwig's feedback from 02/05: Remove
+         macros putLunHigh, putLunLow. Use lpfc_put_lun() inline instead.
+       * Integrated Christoph Hellwig's feedback from 02/05: Instead of
+         cpu_to_be32(), use swab16((uint16_t)lun). This is the same as
+         "swab16() on LE" and "<<16 on BE".
+       * Added updates for revised FC remote port patch (dev_loss_tmo
+         moved to rport, hostdata renamed dd_data, add fc_remote_host()
+         on shutdown).
+       * Removed unnecessary function prototype.
+       * Added code to prevent waking up worker thread after the exit of
+         worker thread.  Fixes panic seen with insmod/rmmod testing with
+         70 disks.
+       * Integrated Christoph Hellwig's patch from 1/30: Make some
+         variables/code static (namely lpfcAlpaArray and
+         process_nodev_timeout()).
+       * Integrated Christoph Hellwig's patch from 1/30: Use
+         switch...case instead of if...else if...else if while decoding
+         JDEC id.
+
+Changes from 20050201 to 20050208
+
+       * Changed version number to 8.0.23
+       * Make lpfc_work_done, lpfc_get_scsi_buf,
+         lpfc_mbx_process_link_up, lpfc_mbx_issue_link_down and
+         lpfc_sli_chipset_init static.
+       * Cleaned up references to list_head->next field in the driver.
+       * Replaced lpfc_discq_post_event with lpfc_workq_post_event.
+       * Implmented Christoph Hellwig's review from 2/5: Check for return
+         values of kmalloc.
+       * Integrated Christoph Hellwig's patch from 1/30: Protecting
+         scan_tmo and friends in !FC_TRANSPORT_PATCHES_V2 &&
+         !USE_SCAN_TARGET.
+       * Integrated Christoph Hellwig's patch from 1/30: Some fixes in
+         the evt handling area.
+       * Integrated Christoph Hellwig's patch from 1/30: Remove usage of
+         intr_inited variable. The interrupt initilization from OS side
+         now happens in lpfc_probe_one().
+       * Integrated Christoph Hellwig's patch from 1/30: remove shim
+         lpfc_alloc_transport_attr - remove shim lpfc_alloc_shost_attrs -
+         remove shim lpfc_scsi_host_init - allocate phba mem in scsi's
+         hostdata readjust code so that they are no use after free's
+         (don't use after scsi_host_put) - make lpfc_alloc_sysfs_attr
+         return errors
+       * Fixed panic in lpfc_probe_one(). Do not delete in a list
+         iterator that is not safe.
+       * Clean up fast lookup array of the fcp_ring when aborting iocbs.
+       * Following timeout handlers moved to the lpfc worker thread:
+         lpfc_disc_timeout, lpfc_els_timeout, lpfc_mbox, lpfc_fdmi_tmo,
+         lpfc_nodev_timeout, lpfc_els_retry_delay.
+       * Removed unused NLP_NS_NODE #define.
+       * Integrated Christoph Hellwig's patch from 1/30: remove unused
+         lpfc_hba_list; remove unused lpfc_rdrev_wd30; remove
+         lpfc_get_brd_no and use Linux provided IDR.
+       * Changed board reset procedure so that lpfc_sli_send_reset()
+         writes the INITFF bit and leaves lpfc_sli_brdreset() to clear
+         the bit.
+       * Removed outfcpio sysfs device attribute.
+       * VPD changes: 1) Modify driver to use the model name and
+         description from the VPD data if it exists 2) Rework use of DUMP
+         mailbox command to support HBAs with 256 bytes of SLIM.
+       * Fixed compile error for implicit definition of struct
+         scsi_target
+
+Changes from 20050124 to 20050201
+
+       * Changed version number to 8.0.22
+       * Moved discovery timeout handler to worker thread. There are
+         function calls in this function which are not safe to call from
+         HW interrupt context.
+       * Removed free_irq from the error path of HBA initialization.
+         This will fix the free of uninitialised IRQ when config_port
+         fails.
+       * Make sure function which processes unsolicited IOCBs on ELS ring
+         still is called with the lock held.
+       * Clear LA bit from work_ha when we are not supposed to handle LA.
+       * Fix double locking bug in the error handling part of
+         lpfc_mbx_cmpl_read_la.
+       * Implemented fast IOCB processing for FCP ring.
+       * Since mboxes are now unconditionally allocated outside of the
+         lock, free them in cases where they are not used.
+       * Moved out a couple of GFP_ATOMICs in lpfc_disc_timeout, to
+         before locks so that they can GFP_KERNEL instead. Also cleaned
+         up code.
+       * Collapsed interrupt handling code into one function.
+       * Removed event posting and handling of solicited and unsolicited
+         iocbs.
+       * Remove ELS ring handling leftovers from the lpfc_sli_inter().
+       * ELS ring (any slow ring) moved from the lpfc_sli_inter() into a
+         worker thread.  Link Attention, Mbox Attention, and Error
+         Attention, as well as slow rings' attention is passed to the
+         worker thread via worker thread copy of Host Attention
+         register. Corresponding events are removed from the event queue
+         handling.
+       * Add entries to hba structure to delegate some functionality from
+         the lpfc_sli_inter() to a worker thread.
+       * Reduced used of GFP_ATOMIC for memory allocations.
+       * Moved locks deeper in order to change GFP_ATOMIC to GFP_KERNEL.
+       * IOCB initialization fix for Raw IO.
+       * Removed qcmdcnt, iodonecnt, errcnt from lpfc_target and from
+         driver.
+       * Added call to lpfc_els_abort in lpfc_free_node.  Modified
+         lpfc_els_abort to reset txq and txcmplq iterator after a
+         iocb_cmpl call.
+       * Fixed a use after free issue in lpfc_init.c.
+       * Defined default mailbox completion routine and removed code in
+         the sli layer which checks the mbox_cmpl == 0 to free mail box
+         resources.
+       * In lpfc_workq_post_event, clean up comment formatting and remove
+         unneeded cast of kmalloc's return.
+       * Removed loop which calls fc_remote_port_unblock and
+         fc_remote_port_delete for every target as this same effect is
+         accomplished by the scsi_remove_host call.
+       * Minor cleanup of header files.  Stop header files including
+         other header files.  Removed sentinels which hide multiple
+         inclusions.  Removed unneeded #include directives.
+       * Fixed memory leaks in mailbox error paths.
+       * Moved lock from around of lpfc_work_done to lpfc_work_done
+         itself.
+       * Removed typedef for LPFC_WORK_EVT_t and left just struct
+         lpfc_work_evt to comply with linux_scsi review coding style.
+       * Fixed some trailing whitespaces, spaces used for indentation and
+         ill-formatting multiline comments.
+       * Bug fix for Raw IO errors.  Reuse of IOCBs now mandates setting
+         of ulpPU and fcpi_parm to avoid incorrect read check of Write IO
+         and incorrect read length.
+
+Changes from 20050110 to 20050124
+
+       * Changed version number to 8.0.21
+       * Removed unpleasant casting in the definition and use of
+         lpfc_disc_action function pointer array.
+       * Makefile cleanup.  Use ?= operator for setting default
+         KERNELVERSION and BASEINCLUDE values.  Use $(PWD) consistently.
+       * Removed call to lpfc_sli_intr from lpfc_config_port_post.  All
+         Linux systems will service hardware interrupts while bringing up
+         the driver.
+       * Christoph Hellwig change request: Reorg of contents of
+         lpfc_hbadisc.c, lpfc_scsi.h, lpfc_init.c, lpfc_sli.c,
+         lpfc_attr.c, lpfc_scsi.c.
+       * Renamed discovery thread to lpfc_worker thread.  Moved handling
+         of error attention and link attention and mbox event handler to
+         lpfc_worker thread.
+       * Removed .proc_info and .proc_name from the driver template and
+         associated code.
+       * Removed check of FC_UNLOADING flag in lpfc_queuecommand to
+         determine what result to return.
+       * Move modification of FC_UNLOADING flag under host_lock.
+       * Fix IOERR_RCV_BUFFER_WAITING handling for CT and ELS subsystem.
+       * Workaround firmware bug for IOERR_RCV_BUFFER_WAITING on ELS
+         ring.
+       * Fixed a couple lpfc_post_buffer problems in lpfc_init.c.
+       * Add missing spaces to the parameter descriptions for
+         lpfc_cr_delay, lpfc_cr_count and lpfc_discovery_threads.
+       * Lock before calling lpfc_sli_hba_down().
+       * Fix leak of "host" in the error path in the remove_one() path.
+       * Fix comment for lpfc_cr_count.  It defaults to 1.
+       * Fix issue where we are calling lpfc_disc_done() recursively from
+         lpfc_linkdown(), but list_for_each_entry_safe() is not safe for
+         such use.
+       * Bump lpfc_discovery_threads (count of outstading ELS commands in
+         discovery) to 32
+       * If the SCSI midlayer tries to recover from an error on a lun
+         while the corresponding target is in the NPR state, lpfc driver
+         will reject all the resets. This will cause the target to be
+         moved to offline state and block all the I/Os. The fix for this
+         is to delay the lun reset to a target which is not in MAPPED
+         state until the target is rediscovered or nodev timeout is
+         fired.
+
+Changes from 20041229 to 20050110
+
+       * Changed version number to 8.0.20
+       * rport fix: use new fc_remote_port_rolechg() function instead of
+         direct structure change
+       * rport fix: last null pointer check
+       * Phase II of GFP_ATOMIC effort.  Replaced iocb_mem_pool and
+         scsibuf_mem_pool with kmalloc and linked list.  Inserted list
+         operations for mempool_alloc calls.  General code cleanup.  All
+         abort and reset routines converted.  Handle_ring_event
+         converted.
+       * If the mbox_cmpl == lpfc_sli_wake_mbox_wait in
+         lpfc_sli_handle_mb_event, pmb->context1 points to a waitq. Do
+         not free the structure.
+       * rport fixes: fix for rmmod crash
+       * rport fixes: when receiving PRLI's, set node/rport role values
+       * rport fixes: fix for unload and for fabric port deletes
+       * VPD info bug fix.
+       * lpfc_linkdown() should be able to process all outstanding events
+         by calling lpfc_disc_done() even if it is called from
+         lpfc_disc_done() Moving all events from phba->dpc_disc to local
+         local_dpc_disc prevents those events from being processed.
+         Removing that queue. From now on we should not see "Illegal
+         State Transition" messages.
+       * Release host lock and enable interrupts when calling
+         del_timer_sync()
+       * All related to rports: Clean up issues with rport deletion
+         Convert to using block/unblock on list remove (was del/add)
+         Moved rport delete to freenode - so rport tracks node.
+       * rport fixes: for fport, get maxframe and class support
+         information
+       * Added use of wait_event to work with kthread interface.
+       * Ensure that scsi_transport_fc.h is always pulled in by
+         lpfc_scsiport.c
+       * In remote port changes: no longer nulling target->pnode when
+         removing from mapped list. Pnode get nulled when the node is
+         freed (after nodev tmo). This bug was causing i/o recieved in
+         the small window while the device was blocked to be errored w/
+         did_no_connect. With the fix, it returns host_busy
+         (per the pre-remote port changes).
+       * Merge in support for fc transport remote port use. This removes
+         any consistent bindings within the driver. All scanning is now
+         on a per-target basis driven by the discovery engine.
+
+Changes from 20041220 to 20041229
+
+       * Changed version number to 8.0.19
+       * Fixed bug for handling RSCN type 3.  Terminate RSCN mode
+         properly after ADISC handling completes.
+       * Add list_remove_head macro.  Macro cleans up memory allocation
+         list handling.  Also clean up lpfc_reset_bus_handler - routine
+         does not need to allocate its own scsi_cmnd and scsi_device
+         structures.
+       * Fixed potential discovery bug, nlp list corrutpion fix potential
+         memory leak
+       * Part 1 of the memory allocation rework request by linux-scsi.
+         This effort fixes the number of bdes per scsi_buf to 64, makes
+         the scatter-gather count a module parameter, builds a linked
+         list of scsi_bufs, and removes all dependencies on lpfc_mem.h.
+       * Reverted lpfc_do_dpc, probe_one, remove_one to original
+         implementation.  Too many problems (driver not completing
+         initial discovery, and IO not starting to disks).  Backs out
+         kthread patch.
+       * Fix race condition in lpfc_do_dpc.  If wake_up interrupt occurs
+         while lpfc_do_dpc is running disc_done and the dpc list is
+         empty, the latest insertion is missed and the schedule_timeout
+         does not wakeup.  The sleep interval is MAX_SCHEDULE_TIMEOUT
+         defined as ~0UL >> 1, a very large number.  Hacked it to 5*HZ
+         for now.
+       * Fixed bug introduced when discovery thread implementation was
+         moved to kthread. kthread_stop() is not able to wake up thread
+         waiting on a semaphore and "modprobe -r lpfc" is not always
+         (most of the times) able to complete. Fix is in not using
+         semaphore for the interruptable sleep.
+       * Small Makefile cleanup - Remove remnants of 2.4 vs. 2.6
+         determination.
+
+Changes from 20041213 to 20041220
+
+       * Changed version number to 8.0.18
+       * Janitorial cleanup after removal of sliinit and ringinit[] ring
+         statistic is owned by the ring and SLI stats are in sli
+         structure.
+       * Integrated patch from Christoph Hellwig <hch@lst.de> Kill
+         compile warnings on 64 bit platforms: %variables for %llx format
+         specifiers must be caste to long long because %(u)int64_t can
+         just be long on 64bit platforms.
+       * Integrated patch from Christoph Hellwig <hch@lst.de> Removes
+         dead code.
+       * Integrated patch from Christoph Hellwig <hch@lst.de>: use
+         kthread interface.
+       * Print LPFC_MODULE_DESC banner in module init routine.
+       * Removed sliinit structure and ringinit[] array.
+       * Changed log message number from 324 to 326 in lpfc_sli.c.
+       * Wait longer for commands to complete in lpfc_reset_bus_handler
+         and lpfc_reset_bus_handler.  Also use schedule_timeout() instead
+         of msleep() and add error message in lpfc_abort_handler()
+       * When setting lpfc_nodev_tmo, from dev_loss set routine, make 1
+         sec minimum value.
+       * Functions which assume lock being held were called without lock
+         and kernel complained about unlocking lock which is not locked.
+       * Added code in linkdown to unreg if we know login session will be
+         terminated.
+       * Removed automap config parameter and fixed up use_adisc logic to
+         include FCP2 devices.
+
+Changes from 20041207 to 20041213
+
+       * Changed version number to 8.0.17
+       * Fix sparse warnings by adding __iomem markers to lpfc_compat.h.
+       * Fix some sparse warnings -- 0 used as NULL pointer.
+       * Make sure there's a space between every if and it's (.
+       * Fix some overly long lines and make sure hard tabs are used for
+         indentation.
+       * Remove all trailing whitespace.
+       * Integrate Christoph Hellwig's patch for 8.0.14: if
+         pci_module_init fails we need to release the transport template.
+         (also don't print the driver name at startup, linux drivers can
+         be loaded without hardware present, and noise in the log for
+         that case is considered unpolite, better print messages only for
+         hardware actually found).
+       * Integrate Christoph Hellwig's patch for 8.0.14: Add missing
+         __iomem annotations, remove broken casts, mark functions static.
+         Only major changes is chaning of some offsets from word-based to
+         byte-based so we cans simply do void pointer arithmetics (gcc
+         extension) instead of casting to uint32_t.
+       * Integrate Christoph Hellwig's patch for 8.0.14: flag is always
+         LPFC_SLI_ABORT_IMED, aka 0 - remove dead code.
+       * Modified preprocessor #ifdef, #if, #ifndef to reflect upstream
+         kernel submission.  Clean build with make clean;make and make
+         clean;make ADVANCED=1 on SMP x86, 2.6.10-rc2 on RHEL 4 Beta
+         1. IO with a few lips and a long cable pull behaved accordingly.
+       * Implement full VPD support.
+       * Abort handler will try to wait for abort completion before
+         returning.  Fixes some panics in iocb completion code path.
+
+Changes from 20041130 to 20041207
+       
+       * Changed version number to 8.0.16
+       * Hung dt session fix.  When the midlayer calls to abort a scsi
+         command, make sure the driver does not complete post-abort
+         handler.  Just NULL the iocb_cmpl callback handler and let SLI
+         take over.
+       * Add Read check that uses SLI option to validate all READ data
+         actually received.
+
+
+Changes from 20041123 to 20041130
+
+       * Changed version number to 8.0.15
+       * Ifdef'd unused "binary" attributes by DFC_DEBUG for clean
+         compiles
+       * Stop DID_ERROR from showing up along with QUEUE_FULL set by the
+         Clarion array (SCSI error ret. val.  0x70028) There is no need
+         for driver to hard fail command which was failed by the target
+         device.
+       * Fix for Scsi device scan bug reported on SourceForge.  Driver
+         was returning a DID_ERROR in lpfc_handle_fcp_error causing
+         midlayer to mark report luns as failing even though it
+         succeeded.
+       * Don't ignore SCSI status on underrun conditions for inquiries,
+         test unit ready's, etc.  This was causing us to lose
+         reservation conflicts, etc
+
+Changes from 20041018 to 20041123
+       
+       * Changed version number to 8.0.14
+       * Added new function "iterator" lpfc_sli_next_iocb_slot() which
+         returns pointer to iocb entry at cmdidx if queue is not full.
+         It also updates next_cmdidx, and local_getidx (but not cmdidx)
+       * lpfc_sli_submit_iocb() copies next_cmdidx into cmdidx. Now it is
+         the only place were we are updating cmdidx.
+       * lpfc_sli_update_ring() is split in to two --
+         lpfc_sli_update_ring() and lpfc_sli_update_full_ring().
+       * lpfc_sli_update_ring() don't to read back correct value of
+         cmdidx.
+       * Simplified lpfc_sli_resume_iocb() and its use.
+       * New static function lpfc_sli_next_iocb(phba, pring, &piocb) to
+         iterate through commands in the TX queue and new command (at the
+         end).
+       * Reduced max_lun to 256 (due to issues reported to some arrays).
+         Fixed comment, and macro values so def=256, min=1, max=32768.
+       * Fix an obvious typo/bug: kfree was used to free lpfc_scsi_buf
+         instead of mempool_free in lpfc_scsiport.c.
+       * Suppress nodev_tmo message for FABRIC nodes.
+       * Fixed some usage of plain integer as NULL pointer.
+       * Bug fix for FLOGI cmpl, lpfc_els_chk_latt error path code
+         cleanup.
+       * Fixup lpfc_els_chk_latt() to have Fabric NPorts go thru
+         discovery state machine as well.
+       * Fixes to lpfc_els_chk_latt().
+       * Use DID not SCSI target id as a port_id and add some missing
+         locks in lpfc_fcp.c.
+       * Changed eh_abort_handler to return FAILED if command is not
+         found in driver.
+       * Fix crash: paging request at virtual address 0000000000100108 -
+         a result of removing from the txcmpl list item which was already
+         removed (100100 is a LIST_POISON1 value from the next pointer
+         and 8 is an offset of the "prev") Driver runs out of iotags and
+         does not handle that case well. The root of the proble is in the
+         initialization code in lpfc_sli.c
+       * Changes to work with proposed linux kernel patch to support
+         hotplug.
+       * Zero out seg_cnt in prep_io failure path to prevent double sg
+         unmap calls.
+       * Fix setting of upper 32 bits for Host Group Ring Pointers if in
+         SLIM. Old code was inappropriately masking off low order bits.
+       * Use scsi_[activate|deactivate]_tcq calls provided in scsi_tcq.h.
+       * Integrated patch from Christoph Hellwig (hch@lst.de): don't call
+         pci_dma_sync_* on coherent memory. pci_dma_sync_* is need and
+         must be used only with streaming dma mappings pci_map_*, not
+         coherent mappings.  Note: There are more consistent mappings
+         that are using pci_dma_sync calls. Probably these should be
+         removed as well.
+       * Modified lpfc_free_scsi_buf to accomodate all three scsi_buf
+         free types to alleviate miscellaneous panics with cable pull
+         testing.
+       * Set hotplug to default 0 and lpfc_target_remove to not remove
+         devices unless hotplug is enabled.
+       * Fixed discovery bug: plogi cmpl uses ndlp after its freed.
+       * Fixed discovery bug: rnid acc cmpl, can potentially use ndlp
+         after its freed.
+       * Modularize code path in lpfc_target_remove().
+       * Changes to support SCSI hotplug (ifdef'ed out because they need
+         kernel support USE_SCAN_TARGET requires kernel support to export
+         the interface to scsi_scan_target and to move the SCAN_WILD_CARD
+         define to a general scsi header file.  USE_RESCAN_HOST requires
+         kernel support to export an interface to scan_scsi_host() with
+         the rescan flag turned on).
+       * Removed redundant variable declaration of lpfc_linkdown_tmo.
+       * Fix for large port count remove test.
+       * Added check to see if BAR1 register is valid before using BAR1
+         register for programming config_port mail box command.
+       * Added lpfc_scsi_hotplug to enable/disable driver support of SCSI
+         hotplug.
+       * Changed lpfc_disc_neverdev() to lpfc_disc_illegal() and changed
+         lpfc_disc_nodev() to lpfc_disc_noop().  Adjusted appropriate
+         events to use these routines.
+       * Add support for SCSI device hotplug.
+       * Take dummy lpfc_target's into account for lpfc_slave_destroy().
+       * Bug fix to store WWPN / WWNN in NameServer / FDMI lpfc_nodelist
+         entries.
+       * Added slavecnt in lpfc_target for diagnostic purposes.
+       * Added lpfc_hba load/unload flags to take care of special cases
+         for add/remove device.
+       * Have target add/remove delay before scanning.
+       * Have rmmod path cleanup blocked devices before scsi_remove_host.
+       * Added a #define for msleep for 2.6.5 kernels.
+       * In reset bus handler if memory allocation fails, return FAILED
+         and not SUCCESS.
+       * Have lpfc eh handlers, bus_reset and lun_reset, wait for all
+         associated I/Os to complete before returning.
+       * Fix memset byte count in lpfc_hba_init so that
+         LP1050 would initialize correctly.
+       * Backround nodev_timeout processing to DPC This enables us to
+         unblock (stop dev_loss_tmo) when appopriate.
+       * Fix array discovery with multiple luns.  The max_luns was 0 at
+         the time the host structure was intialized.  lpfc_cfg_params
+         then set the max_luns to the correct value afterwards.
+       * Remove unused define LPFC_MAX_LUN and set the default value of
+         lpfc_max_lun parameter to 512.
+       * Reduced stack usage of lpfc_hba_init.
+       * Cleaned up the following warning generated by
+         scripts/checkincludes.pl lpfc_fcp.c: scsi/scsi_cmnd.h is
+         included more than once.
+       * Replaced "set_current_state(TASK_UNINTERRUPTIBLE);
+         schedule_timeout(timeout)" with "msleep(timeout)".
+       * Fixnode was loosing starget when rediscovered. We saw messages
+         like: lpfc 0000:04:02.0: 0:0263 Cannot block scsi target as a
+         result.  Moved starget field into struct lpfc_target which is
+         referenced from the node.
+       * Add additional SLI layer logging in lpfc_sli.c.
+       * Ignore more unexpected completions in lpfc_nportdisc.c.
+       * Can not call lpfc_target_unblock from the soft interrupt
+         context.  It seems to be not nessasery to unblock target from
+         nodev timeout.
+       * Introduce and use less lethal event handler for unexpected
+         events in lpfc_nportdisc.c.
+       * Can not call fc_target_(un)block() functions with interrupts
+         disabled in lpfc_scsiport.c.
+       * Added new configuration parameter, lpfc_max_luns range 1-32768,
+         default 32768.
+       * Allow lpfc_fcp.c to call lpfc_get_hba_sym_node_name().
+       * Increase nodev timeout from 20 seconds to 30 seconds.
+       * Replace some kfree((void*)ptr) with kfree(ptr).
+       * Make 3 functions static: lpfc_get_hba_sym_node_name,
+         lpfc_intr_prep and lpfc_setup_slim_access.  Move lpfc_intr_prep
+         and lpfc_setup_slim_access so they're defined before being used.
+       * Remove an unecessary list_del() in lpfc_hbadisc.c.
+       * Set nlp_state before calling lpfc_nlp_list() since this will
+         potentially call fc_target_unblock which may cause a race in
+         queuecommand by releasing host_lock.
+       * Since lpfc_nodev_tmo < dev_loss_tmo remove queuecommand
+         DID_BAD_TARGET return for now.
+       * Fix a problem with rcv logo.
+       * Remove unused portstatistics_t structure.
+       * Remove #if 0 and unnecessary checks in lpfc_fcp.c.
+       * Simplify lpfc_issue_lip: Extra layer of protection removed.
+       * Grab lock before calling lpfc_sli_issue_mbox(phba, pmb,
+         MBX_NOWAIT) in lpfc_sli_issue_mbox_wait().
+
+Changes from 20040920 to 20041018
+
+       * Changed version number to 8.0.13
+       * Hide some attributes using #ifndef DFC_DEBUG ... #endif.
+       * Modify Makefile to (1) make BUILD_NO_DEBUG=1 will hide some
+         (binary) attributes (2) make BUILD_FC_TRANS=0 will build driver
+         for 2.6.5 kernel with block/unblock patch.
+       * Modified #ifdef names.
+       * Added support for proposed FC transport host attributes (which
+         replaces some of the attributes we had local to the driver).
+         Removed the binary statistics sysfs attribute.
+       * Added extra ELS verbose logging for ELS responses.
+       * Added recognition for BUILD_FC_TRANS=2 to Makefile to define
+         FC_TRANS_VER2.
+       * Add a pointer for link stats allocation.
+       * Exported lpfc_get_hba_sym_node_name for use by FC_TRANS_VER2
+         sysfs routines.
+       * Fix discovery problem in lip testing: if device sends an ELS cmd
+         (i.e. LOGO) before our FLOGI completes it should be LS_RJT'ed.
+       * Moved #defines around to provide target_add/remove for upstream
+         kernel deliverables only not SLES9.  Provided ifdefs to #include
+         target_block/unblock only if FC_TRANS_VER1.
+       * Add sanity check in lpfc_nlp_list move setting nlp_Target
+         outside #ifdef.
+       * Added a blocked member to the lpfc_target structure for
+         block/unblock.  This member allows the driver to know when to
+         unblock for pci_remove_one or pci_add_one.  #ifdef'd some more
+         block/unblock stuff and removed some defensive checks from
+         target_block/unblock.
+       * Moved + 5 second window to dev_loss_tmo setting and updated
+         comments.
+       * Removed NULL target check from target_block/unblock and fixed up
+         a few comments.
+       * Enable sysfs attributes on 2.6.5 kernels and remove extra
+         compatibility code.
+       * Remove any and all trailing whitespace.
+       * Added message 0718 and return error when dma_map_single fails.
+       * Changed the fcpCntl2 commands to include an FCP_ prefix to get
+         rid of build warnings on later 2.6.9-rc kernels.  Build
+         conflicts with scsi/scsi.h.  Remove inclusions of scsi/scsi.h
+         from hbadisc.c, sli.c, and fcp.c since these modules had no
+         dependencies on scsi.h.
+       * Fixed a bug with RSCN handling. A RSCN received on one device,
+         shouldn't affect other devices not referenced by the RSCN.
+       * Moved #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,6) to include
+         lpfc_jedec_to_ascii to prevent warning in SLES 9.
+       * Update Makefile to account for SLES 9 and scsi-target upstream
+         kernel.
+       * This checkin provides block/unblock hooks for the upstream scsi
+         target kernel and 2.6.5 on SLES9 SP1 with the block/unblock
+         patch.
+       * Discovery changes regarding setting targetp->pnode and
+         ndlp->nlp_Target Ensure fc_target_* routines are called properly
+         from discovery.  Remove list_del's from lpfc_cleanup().  Ensure
+         all the lpfc_consistent_bind_* routines don't set any driver
+         structure objects.
+       * Fix for timeout of READ_LA or READ_SPARAM mailbox command
+         causing panic.
+       * Cleanup list_del()'s for Discovery ndlp lists.
+       * Bug fixes for some insmod/rmmod crashes, link down crashes and
+         device loss crashes.
+       * Removed NLP_SEARCH_DEQUE.
+       * Call lpfc_target_unblock only if the targetp is nonNull and with
+         the host_lock held.
+       * Added qcmdcnt back along with misc bug fixes to discovery.
+       * Changed tgt_io to outfcpio lpfc_fcp.c.
+       * Fixed errors caused by LIP and cable pulls both with and without
+         block/unblock patch.
+       * For now we have to call fc_target_unblock and fc_target_block
+         with interrupts enabled.
+       * Save seg_cnt from dma_map_sg.  Save scatter-gather start address
+         and pass back to dma_unmap_sg in error with seg_cnt.
+       * Incorporating block/unblock calls into driver with ifdefs.  This
+         change is supported by scsi-target-2.6 kernel and forward only.
+       * Merged in some discovery bug fixes and added tgt io counters.
+       * Added sysfs attributes/interfaces: read only attribute
+         "management_version" and write only attribute "issue_lip".
+       * Fix build on big endian machines: while #if was OK with
+         __BIG_ENDIAN which defined as 4321, __BIG_ENDIAN_BITFIELD has to
+         be tested with #ifdef because it does not have any value, it is
+         either defined or not.
+       * Add fabric_name and port_type attributes.
+       * Change mdelay to msleep.  mdelay works, but wastefully uses cpu
+         resources without a lock held. Revert to msleep.  Tested with
+         sg_reset for bus and three attached targets.
+       * Added the customary #ifndef...#define...#endif to
+         lpfc_version.h.
+       * Integrate patches from Christoph Hellwig: two new helpers common
+         to lpfc_sli_resume_iocb and lpfc_sli_issue_iocb - singificant
+         cleanup of those two functions - the unused SLI_IOCB_USE_TXQ is
+         gone - lpfc_sli_issue_iocb_wait loses it's flags argument
+         totally.
+       * Fix in lpfc_sli.c: we can not store a 5 bit value in a 4-bit
+         field.
+       * Moved some routines out of lpfc_fcp.c into more appropriate
+         files.
+       * Whitespace cleanup: remove all trailing whitespace.
+       * Make lpfc_disc_ndlp_show static to lpfc_fcp.c.
+       * Remove leftover printk and replace some with
+         printk(KERN_WARNING)
+       * Trivial: fix a few long lines and a soft tab.
+       * Remove warnings generated by Sparse against driver (make
+         C=1). Mostly these are "using integer as pointer warnings"
+         i.e. use NULL instead of 0.
+       * Integrated patch from Christoph Hellwig: Quite a lot of changes
+         here, the most notable is that the phba->slim2p lpfc_dmabuf goes
+         away in favour of a typede pointer and a dma_addr_t.  Due to the
+         typed pointer lots of the cast mess can go away, and while at it
+         I also replaced the messy SLI2_SLIM_t with a simple struct
+         lpfc2_sli2_slim that only contains the part of the union we care
+         about while using SLI2_SLIM_SIZE for all size calculations
+         directly.
+       * Integrated patch from Christoph Hellwig: This streamlines the
+         I/O completion path a little more, especially taking care of
+         fast-pathing the non-error case.  Also removes tons of dead
+         members and defines from lpfc_scsi.h - e.g. lpfc_target is down
+         to nothing more then the lpfc_nodelist pointer.
+       * Added binary sysfs file to issue mbox commands
+       * Replaced #if __BIG_ENDIAN with #if __BIG_ENDIAN_BITFIELD for
+         compatibility with the user space applications.
+       * Decrease the amount of data in proc_info.
+       * Condense nodelist flag members.
+       * Expand INFO for discovery sysfs shost entries.
+       * Notify user if information exceeds 4k sysfs limit.
+       * Removed a bunch of unused #defines.
+       * Added initial sysfs discovery shost attributes.
+       * Remove unused #defines lpfc_disc.h.
+       * Fixed failMask nodelist settings.
+       * Cleanup some old comments / unused variables.
+       * Add LP101 to list of recognized adapters.
+
+Changes from 20040908 to 20040920
+
+       * Changed version number to 8.0.12
+       * Removed used #defines: DEFAULT_PCI_LATENCY_CLOCKS and
+         PCI_LATENCY_VALUE from lpfc_hw.h.
+       * Changes to accomodate rnid.
+       * Fix RSCN handling so RSCN NS queries only effect NPorts found in
+         RSCN data.
+       * If we rcv a plogi on a NPort queued up for discovery, clear the
+         NLP_NPR_2B_DISC bit since rcv plogi logic will force NPort thru
+         discovery.
+       * Ensure lpfc_target is also cleaned up in lpfc_cleanup().
+       * Preliminary changes for block/unblock kernel API extensions in
+         progress with linux-scsi list.  These are name changes and
+         prototype changes only.
+       * Added send_abts flag to lpfc_els_abort. For rcv LOGO when ADISC
+         sent, the XRI of the LOGO rcv'ed is the same as the ADISC
+         sent. Thus we cannot ABTS the ADISC before sending the LOGO ACC.
+       * Weed out some unused fc_flags.  Add FC_DISC_TMO.
+       * board_online sysfs attribute added to support libdfc functions
+         InitDiagEnv and SetBrdEnv.
+       * Streamline code in lpfc_els_retry fixup abort case in
+         lpfc_els_timeout_handler().
+       * Flush discovery/ELS events when we bring SLI layer down.
+       * ctlreg and slimem binary attributes added to support libdfc
+         read/write mem/ctl functions.
+       * Integrated Christoph Hellwig's patch: Cleanup
+         lpfc_sli_ringpostbuf_get.
+       * Modified lpfc_slave_alloc and lpfc_slave_destroy to allocate and
+         free a dummy target pointer.  This allows queuecommand to skip
+         the NULL target pointer check and avoid the console spam when
+         slave_alloc fails.
+       * Fix cfg_scan_down logic, it was reversed.
+       * Init list head ctrspbuflist.
+       * Change name of lpfc_driver_abort to lpfc_els_abort since it is
+         only valid for ELS ring.
+       * Remove unused third argument for lpfc_consistent_bind_get().
+       * Fix up iotag fields in lpfc_prep_els_iocb().
+       * Remove log message on code path triggered by lpfc_els_abort().
+       * Set host->unique_id in lpfc_fcp.c.
+       * Removed deadwood: lpfc_target.pHba not necessary anymore.
+       * Integrated patch from Christoph Hellwig: remove dead
+         SLI_IOCB_POLL handling.
+       * Integrated patch from Christoph Hellwig: Streamline I/O
+         submission and completion path a little.
+       * Remove unnecessary lpfc_brd_no.  Ensure brd_no assignment is
+         unique.
+       * Removed unused MAX_FCP_LUN.
+       * Use mod_timer instead of add_timer for fdmi in lpfc_ct.c.
+       * Fixed misc discovery problems.
+       * Move stopping timers till just before lpfc_mem_free() call.
+       * Fix up NameServer reglogin error path.
+       * Cleanup possible outstanding discovery timers on rmmod.
+       * Fix discovery NPort to NPort pt2pt problem.
+       * Get rid of ip_tmofunc / scsi_tmofunc.
+       * Integrated patch from Christoph Hellwig:
+         lpfc_disc_done/lpfc_do_dpc cleanup - lpfc_disc_done can return
+         void - move lpfc_do_dpc and lpfc_disc_done to lpfc_hbadisc.c -
+         remove checking of list emptiness before calling lpfc_disc_done,
+         it handles the emtpy list case just fine and the additional
+         instructions cost less then the bustlocked spinlock operations.
+       * Integrated patch from Christoph Hellwig: This adds a new 64bit
+         counter instead, brd_no isn't reused anymore.  Also some tiny
+         whitespace cleanups in surrounding code.
+       * Reorder functions in lpfc_els.c to remove need for prototypes.
+       * Removed unsed prototypes from lpfc_crtn.h -
+         lpfc_ip_timeout_handler, lpfc_read_pci and lpfc_revoke.
+       * Removed some unused prototypes from lpfc_crtn.h -
+         lpfc_scsi_hba_reset, lpfc_scsi_issue_inqsn,
+         lpfc_scsi_issue_inqp0, lpfc_scsi_timeout_handler.
+       * Integrated patch from Christoph Hellwig: remove TRUE/FALSE
+         usage.
+       * Integrated patch from Christoph Hellwig: Remove unused function
+         prototypes lpfc_set_pkt_len and lpfc_get_pkt_data from
+         lpfc_crtn.h - fixes build warnings.
+       * Removed unused struct lpfc_dmabufip definition from lpfc_mem.h.
+       * Removed pre-2.6.5 MODULE_VERSION macro from lpfc_compat.h.
+       * Fixing missing static and removing dead code.
+       * Adding nodewwn, portwwn and portfcid shost attributes.
+       * Initial support for CT via sysfs. request payloads of size less
+         than PAGE_SIZE and rsp payloads of size PAGE_SIZE are supported.
+         Driver maintains a list of rsp's and passes back rsp's
+         corresponding to the pid of the calling process.
+       * Support for RefreshInformation, GetAdapterAttributes,
+         GetPortStatistics.
+       * Make nodev-tmo default to 20 seconds.
+       * Fix up some DSM error cases, unreg_login rpi where needed.

+         Used host_lock for DPC to avoid race (remove dpc_lock)
+       * Fix some corner cases for PLOGI receive - simplify error case
+         for cmpl_reglogin_reglogin_issue.
+       * Bug fix for ppc64 EEH MMIO panic - always do readl after
+         writel's of HBA registers to force flush.

+       * Removed persistent binding code.
+       * Display both ASC and ASCQ info.
+       * Fixed link down->up transitions when linkdown tmo expires. Fix
+         was in the defensive error checking at the start of
+         queuecommand.
+       * Removed lpfc_scsi_timeout_handler as this timer is no longer
+         required.  The midlayer will exhaust retries and then call
+         lpfc_abort_handler, lpfc_reset_lun_handler, and
+         lpfc_reset_target_handler.
+       * Minimal support for SCSI flat space addressing/volume set
+         addressing.  Use 16 bits of LUN address so that flat
+         addressing/VSA will work.
+       * Changed 2 occurences of if( 1 != f(x)) to if(f(x) != 1)

+         functions.
+       * Fix display of node_name and port_name via fc transport
+         attr.
+       * Removed biosparam code.
+       * Removed range checking. phba->config[] array elements are now
+         embedded into the hba struct. lpfc_config_setup() has been
+         removed.
+       * Collapsed lpfc_scsi_cmd_start into lpfc_queuecommand and cleaned
+         up combined routines.

+         lpfc_sched_service_high_priority_queue.
+       * Removed unused function lpfc_nodev.
+       * Removed scsi_cmnd->timeout_per_command cancelation. SCSI midlayer
+         now times out all commands - FW is instructed to not timeout.
+       * Removed polling code from lpfc_scsi_cmd_start. Reorganized
+         queuecommand and cmd_start some.
+
+Changes from 20040810 to 20040823
+
+       * Changed version number to 8.0.10
+       * Additional timer changes as per Arjan / Christoph's comments.
+       * Used mod_timer() instead of del_timer_sync() where appropriate.
+       * Fixed a use after free case (panic on 2.6.8.1 with
+         CONFIG_DEBUG_SLAB set).
+       * Fix compile warning in lpfc_fcp.c.
+       * Minor fix for log message, that prints unassigned brdno which is
+         zero.
+       * Move scsi_host_alloc() to the beginning of probe_one(). This
+         ensures that host_lock is available at later stages and also
+         avoids tons of unnecessary initializing if host_alloc()
+         fails.
+       * Removed else clause from lpfc_slave_configure that set
+         sdev->queue_depth.  The driver informs the midlayer of its
+         setting in the template and only overrides if queue tagging is
+         enabled.
+       * Added PCI_DEVICE_ID_ZEPHYR and PCI_DEVICE_ID_ZFLY (Junior
+         Zephyr) support
+
+Changes from 20040730 to 20040810
+       
+       * Changed version number to 8.0.9
+       * Removed per HBA driver lock.  Driver now uses the host->host_lock
+       * Restored support for the 2.6.5 kernel for those linux distributions
+         shipped with the 2.6.5 kernel.
+       * Applied patch from Christoph Hellwig (hch@infradead.org) as follows
+         "[PATCH] use scsi host private data in ->proc_info.  
+       * Applied patch from Christoph Hellwig (hch@infradead.org) as follows
+         "Re: [Emulex] Ready for next round.  This patch cleans up the memory 
+         allocation routines a little and fixes a missing mempool_destroy and
+         some missing error handling."
+       * Changed pointers assignments from 0 to NULL.
+       * Added fixes to the lpfc_reset_lun_handler and lpfc_reset_bus_handler
+         entry points that caused kernel to Oops or hang.
+       * Added fixes to targetless hosts that caused modprobe and insmod to hang.
+       * Ongoing cleanup to many files
+         
+Changes from 20040723 to 20040730

+         caller.
+       * Removed 2 unneeded arguments to lpfc_find_target (lun and
+         create_flag).
+       * Make lpfc_sli_reset_on_init = 1
+       * Minor cleanup to quieten sparse.
+       * Removed missing function = 0 in tmo routine in lpfc_els.c.
+       * Moved additional binding parameters into lpfc_defaults.c:
+         lpfc_automap / lpfc_fcp_bind_method
+       * Use msecs_to_jiffies() where applicable.
+       * Only use queue depth attribute only after SLI HBA setup was
+         completed.
+       * Put in memory barriers for PPC
+       * Added PCI_DEVICE_ID_HELIOS and PCI_DEVICE_ID_JFLY (Junior
+         Helios) support
+       * Added 4&10 gigabit choices in user option link_speed
+       * Updated timer logic: Set timer data after init_timer use
+         timer_pending() instead of expires.
+       * Removed some remnants of IP over FC support from Kconfig and
+         Makefile.
+       * Remove redundant prototypes for lpfc_handle_eratt,
+         lpfc_handle_latt and lpfc_read_pci.

+         definition. This removes the need for the cruft of forward
+         declarations. Also removing a redundant #define ScsiResult as it
+         already available elsewhere.
+       * Applying "Streamline lpfc error handling" patch from Christoph

+         and newline in the print string rather than in the #define.
+       * Remove code that optionally locates Host Group Pointers in host
+         memory SLIM since this is no longer needed for PPC64, once
+         CONFIG_PORT uses HBA's view of its BAR0.
+       * Removed the forward declarations of the sli functions and
+         rearranging the code in lpfc_sli.c.
+       * Removed the preamble functionality from logging.
+       * Make lpfc_sli_hba_setup() return negative error codes on error
+         and correct the comment left over in lpfc_fcp.c
+       * Removed the lpfc_loadtime variable.
+       * Put a space between all ifs and their open parens '('.

+         kernels at least).
+       * Changing phba->config to kmalloc lpfc_icfgparam and not
+         *phba->config. This is manifesting itself as a panic in
+         pci_release_region().
+       * Fix for firmware download / board reset problem.
+       * Integrated patch from Christoph Hellwig (hch@infradead.org) to
+         reorganize and cleanup lpfc_fcp.c

+         give driver time to rediscover targets before the midlayer
+         retries the SCSI commands.
+
+Changes from 20040604 to 20040614
+
+       * Changed version number to 8.0.4
+       * Removed lpfc_valid_lun function.
+       * Added scsi_buf safety pool to address scsi_buf failures in
+         queuecommand under low memory conditions.  Allocations now come
+         from kmalloc initially, but if kmalloc fails, the allocation
+         comes from the safety pool.
+       * Modified lpfc_slave_alloc to only set the scsi_device->hostdata
+         pointer if the driver has discovered the target.  This routine
+         always returns success now as well since no error ever occurs in
+         the alloc routine.
+       * Mask only info and warning messages.  Print all error messages
+         irrespective of mask.
+       * Removing lpfc_log_chk_msg_disabled()
+       * Changed lpfc_printf_log to take struct lpfc_hba * directly
+         instead of a "board number".
+       * Convert dma_sync_single to pci_dma_sync_single_for_{device/cpu}.
+       * Implemented new style log messages. The message strings are now
+         embedded in the call to lpfc_printf_log.
+       * Decreased FLOGI discovery timeout to 20 seconds.
+       * On error in lpfc_pci_probe_one() return -1 and not 1.
+       * Allow for board numbers that are not sequential, paving the way
+         for hotplug support.
+       * scsi_add_host() can fail, so wrap it around in an if(). Also
+         initiate scsi_scan_host() after attaching the sysfs attributes.
+       * lpfc_release_version is used only in lpfc_ct.c, so move it there
+         and mark it as static.
+       * Removed lpfc_sleep_ms and replaced with mdelay or schedule calls
+         directly
+       * Removed all (struct list_head *) casts from clkData-related list
+         handling in list_add, list_del macros.
+       * Removed EXPORT_SYMBOLs.
+       * Removed LPFC_MIN_QFULL and lpfc_qthrottle_up.
+       * Replace LPFCSCSITARGET_t with struct lpfc_target.
+       * Replace LPFCSCSILUN_t with struct lpfc_lun.
+       * Remove unused struct declarations (fcPathId and fcRouteId) from
+         lpfc_scsi.h.
+       * Rewrite use of FC transport attributes.
+       * Fix crash when link is lost.  This was due to lpfc_delay_iodone
+         calling list_del on an object that was never put on a list.
+       * Remove trailing spaces at the end of all lines.
+       * Set MAX_FCP_TARGET to 256 from 0xff.  Set MAX_FCP_LUN and
+         MAX_FCP_CMDS to their decimal equivalents and updated
+         documentation.
+
+Changes from 20040526 to 20040604
+
+       * Changed version number to 8.0.3
+       * Completed sysfs FC transport support.
+       * Removed unused fields in SCSI LUN and SCSI Target structures:
+         void *pTargetProto; void *pTargetOSEnv; void *pLunOSEnv;
+       * Modified list_for_each to list_for_each_entry. Modified
+         list_for_each_safe to list_for_each_entry_safe.

+       * Changed *pos_tmp -> *postmp, *p_mbuf -> *pmbuf
+       * Following changes are made to the SCSI fast path: Added
+         DMA_BUF_t member to the lpfc_scsi_buf_t.  This will reduce a
+         memory allocation in the scsi fast path.  Added check for
+         targetp == NULL in the scsi fast path.  Increased number of
+         scatter gather entries in lpfc_scsi_dma_ext to 4 from 3 and
+         changed the size of lpfc_scsi_dma_ext to 264
+       * Fixing some missing static lpfc_nportdisc.c.
+       * Reordered #include lines so that lpfc.h doesn't have to #include
+         other header files.
+       * Remove lpfc_get_hba_sym_node_name() as a global EXPORT and make
+         it static.

+         need for the raft of prototypes at the top.
+       * Changed LPFC_BINDLIST_t to struct lpfc_bindlist.
+       * Removed lpfc_issue_ct_rsp(), lpfc_sleep(), lpfc_add_bind(),
+         lpfc_del_bind(), lpfc_sli_wake_mbox_wait() and
+         lpfc_sli_issue_mbox_wait().
+       * Fixed a large number of overly-long lines.
+       * Fixed some discovery problems: Introduced deferred ndlp removal
+         when in DSM to avoid panic when in nested DMSs Fix NportId

+         to determine what to return from queuecommand.
+       * Change return type of lpfc_evt_iocb_free to void as it doesn't

+       * Removed function prototypes for lpfc_start_timer() and
+         lpfc_stop_timer()
+       * Changed timer support to be inline.  Clk_data is now declared

+       * LP9802 qdepth is twice the LP9802DC qdepth.  Delay
+         elx_sched_init after READ_CONFIG to get max_xri from the
+         firmware.  Reset ELX_CFG_DFT_HBA_Q_DEPTH to max_xri after
+         READ_CONFIG
+       * Fix fc_get_cfg_parm() to be more robust and support embedded hex
+         values.  The lpfc_param's are now defined as:
+         lpfc_log_verbose="lpfc:0,lpfc0:0x10,lpfc1:4,lpfc100:0xffff" The
+         "," delimter does not matter. It can be anything or not exist at
+         all. ie param = "lpfc:0lpfc0:0x10.lpfc1:4txtlpfc100:0xffff" will

+         are accessing the device the first time.
+       * Remove assumption in lpfc_reset_lun_handler that a valid
+         lpfc_scsi_buf is hung off of linux's scsi_cmnd->host_scribble
+         when our reset is called.
+
+Changes from 20040507 to 20040515

+
+Changes from 20040409 to 20040416
+
+       * The scsi_register and scsi_alloc_host OS calls can fail and
+         return a zero-valued host pointer.  A ctrl-C on 2.6 kernels
+         during driver load will cause this and the driver to panic.
+         Fixed this bug.  Also found a bug in the error_x handling with
+         lpfc_sli_hba_down - it was in the wrong place and the driver

+         lpfc_ipport.c, lpfc_logmsg.c, lpfc_logmsg.h and lpfc_scsiport.c
+         - mostly replacing groups of 8 spaces with hard tabs and keeping
+         lines to 80 column max..
+       * Removed LPFC_DRVR_LOCK call from lpfc_unblock_requests for 2.4
+         kernels.  The lpfc_scsi_done routine already unlocks the driver

+       * Removed global lock capabilities from driver lock routines
+       * Remove SA_INTERRUPT flag from request_irq

+         to  character device initialization.
+       * Initial support code for discovery in tasklet conversion.
+       * Removing char interface and ioctl code.
+       * Change all elx prefixes to lpfc

+       * Removed lpfc_els_chk_latt from the lpfc_config_post function.
+         lpfc_els_chk_latt will enable the link event interrupts when
+         flogi is pending which causes two discovery state machines
+         running parallely.
+       * Add pci_disable_device to unload path.
+       * Move lpfc_sleep_event from lpfc_fcp.c to lpfc_util_ioctl.c
+       * Call dma_map_single() & pci_map_single() directly instead of via
+         macro lpfc_pci_map().  Allow address 0 for PPC64.
+       * Change sleep to uninterruptible in lpfc_sli_issue_icob_wait
+         because this function doesn't handle signals.

+         send (HBA_Q_DEPTH - 10) cmds.
+       * Clean up code in the error path, check condition.  Remove
+         ununsed sense-related fields in lun structure.

+         make is called in order for the install rule to attempt to
+         copy the lpfndd.o driver.  This change fixes a bug that
+         occurs because the install rule by default attempted to
+         install lpfndd.o, whereas the default make rule did not by
+         default build lpfndd.o.
+       * Keep track if hbaapi index numbers need to be refreshed.
+       * Removed prod_os.h from include list.
+       * Removed LPFC_LOCK and LPFC_UNLOCK macros.  Added OS calls
+         into elx_os_scsiport.c.  This file is now empty.
+       * Added spin_lock_irqsave and spin_unlock_irqrestore calls
+         into code directly and removed LPFC_LOCK_ and _UNLOCK_
+         macros
+       * Remove references to "elx_clock.h"
+       * Added utsname.h to include list.  The previous checkin to
+         elx_os.h removed its inclusion of utsname.h since there is
+         precious little in the file.  However, lpfcLINUXfcp.c needs
+         it and now has it.
+       * Removed some commented-out code
+       * Removed elx_lck_t data structure, stray elxDRVR_t type, and
+         include from file.  No longer used.
+       * Removed two PCI Sync defines.  Removed includes - not
+         needed.  Cleaned up macro lines.
+       * Added two functions from elxLINUXfcp.c.  These functions
+         were IPFC specific.
+       * Removed hipri lock abstractions and added OS call into code.
+         Removed elx_lck_t and added spinlock_t directly. Moved two
+         IPFC functions into lpfc_ipport.c
+       * Moved IP specific structures to lpfc_ip.h file.
+       * lpfc_ipfarp_timeout() uses system timer.  Remove all usages
+         of old internal clock support.
+       * Made changes to compile without IPFC support for the default
+         build.  Added ifdef IPFC for all lpfc_ip.h includes.

+       * Removed elx_sched.o from 2.6 dependencies
+       * Reworked lpfc_pcimap.
+       * Use Linux swap macros to replace ELX swapping macros
+         (SWAP_SHORT, SWAP_LONG, SWAP_DATA, SWAP_DATA16,
+         PCIMEM_SHORT, PCIMEM_LONG, PCIMEM_DATA).
+       * move in_interrupt() check inside of elx_sleep_ms()
+       * Moved location of pci.h include.
+       * Restored elx_lck_t types in elxHBA_t.
+       * Removed elx_pci_dma_sync call.  Also removed some PCI

+          timer.
+       * Removed num_bufs and num_iocbs configuration parameters.
+       * Fixed a memory corruption bug. This was caused by a memory
+         write to ndlp structure from lpfc_cmpl_els_acc function.
+         This ndlp structure was freed from lpfc_els_unsol_event.
+       * lpfc_disc_timeout() and lpfc_establish_link_tmo() now use
+         system timer.  Also update lpfc_els_retry_delay() to do a
+         single lock release at the end.
+       * Remove use of PAN (pseudo adapter number).
+       * Reintroduced usage of the cross compiler for building on

+LPFC Driver Release Notes:
+
+=============================================================================
+
+
+                               IMPORTANT:
+
+  Starting in the 8.0.17 release, the driver began to be targeted strictly
+  toward the upstream kernel. As such, we removed #ifdefs for older kernels
+  (pre 2.6.10). The 8.0.16 release should be used if the driver is to be
+  run on one of the older kernels.
+
+  The proposed modifications to the transport layer for FC remote ports
+  and extended attribute support is now part of the upstream kernel
+  as of 2.6.12. We no longer need to provide patches for this support,
+  nor a *full* version which has old an new kernel support.
+  
+  The driver now requires a 2.6.12 (if pre-release, 2.6.12-rc1) or later
+  kernel.
+  
+  Please heed these dependencies....
+
+
+   ********************************************************************
+
+
+The following information is provided for additional background on the
+history of the driver as we push for upstream acceptance.
+
+Cable pull and temporary device Loss:
+
+  In older revisions of the lpfc driver, the driver internally queued i/o 
+  received from the midlayer. In the cases where a cable was pulled, link
+  jitter, or a device temporarily loses connectivity (due to its cable
+  being removed, a switch rebooting, or a device reboot), the driver could
+  hide the disappearance of the device from the midlayer. I/O's issued to
+  the LLDD would simply be queued for a short duration, allowing the device
+  to reappear or link come back alive, with no inadvertant side effects
+  to the system. If the driver did not hide these conditions, i/o would be
+  errored by the driver, the mid-layer would exhaust its retries, and the
+  device would be taken offline. Manual intervention would be required to
+  re-enable the device.
+
+  The community supporting kernel.org has driven an effort to remove
+  internal queuing from all LLDDs. The philosophy is that internal
+  queuing is unnecessary as the block layer already performs the 
+  queuing. Removing the queues from the LLDD makes a more predictable
+  and more simple LLDD.
+
+  As a potential new addition to kernel.org, the 8.x driver was asked to
+  have all internal queuing removed. Emulex complied with this request.
+  In explaining the impacts of this change, Emulex has worked with the
+  community in modifying the behavior of the SCSI midlayer so that SCSI
+  devices can be temporarily suspended while transport events (such as
+  those described) can occur.  
+
+  The proposed patch was posted to the linux-scsi mailing list. The patch
+  is contained in the 2.6.10-rc2 (and later) patch kits. As such, this
+  patch is part of the standard 2.6.10 kernel.
+
+  By default, the driver expects the patches for block/unblock interfaces
+  to be present in the kernel. No #define needs to be set to enable support.
+
+
+Kernel Support
+
+  This source package is targeted for the upstream kernel only. (See notes
+  at the top of this file). It relies on interfaces that are slowing
+  migrating into the kernel.org kernel.
+
+  At this time, the driver requires the 2.6.12 (if pre-release, 2.6.12-rc1)
+  kernel.
+
+  If a driver is needed for older kernels please utilize the 8.0.16
+  driver sources.
+
+
+Patches
+
+  Thankfully, at this time, patches are not needed.
