This patch adds ATAPI support to the sata_promise driver.
This has been tested on both first- and second-generation
chips (20378 and 20575), and with both SATAPI and PATAPI
devices. CD-writing works.
SATAPI DMA works on second-generation chips, but on
first-generation chips SATAPI is limited to PIO due
to what appears to be HW limitations.
PATAPI DMA works on both first- and second-generation
chips, but requires the separate PATA support patch
before it can be used on TX2plus chips.
The functional changes to the driver are:
- remove ATA_FLAG_NO_ATAPI from PDC_COMMON_FLAGS
- add ->check_atapi_dma() operation to enable DMA for bulk data
transfers but force PIO for other ATAPI commands; this filter
is from Promise's driver and largely matches pata_pdc207x.c
- use a more restrictive ->check_atapi_dma() on first-generation
chips to force SATAPI to always use PIO
- add handling of ATAPI protocols to pdc_qc_prep(), pdc_host_intr(),
and pdc_qc_issue_prot(): ATAPI_DMA is handled by the driver
while non-DMA protocols are handed over to libata generic code
- add pdc_issue_atapi_pkt_cmd() to handle the initial steps in
issuing ATAPI DMA commands before sending the actual CDB;
this procedure was ported from Promise's driver

This patch implements a simple way of setting up per-port
flags on the SATA+PATA Promise TX2plus chips, which is a
prerequisite for supporting the PATA port on those chips.
It is based on the observation that ap->flags isn't really
used until after ->port_start() has been invoked. So it
places the "exceptional" per-port flags array in the driver's
private host structure, and uses it in ->port_start() to
finalise the port's flags.
This patch obsoletes the #promise-sata-pata branch included
in the #all branch.

[PATCH] md: avoid possible BUG_ON in md bitmap handling
md/bitmap tracks how many active write requests are pending on blocks
associated with each bit in the bitmap, so that it knows when it can clear
the bit (when count hits zero).
The counter has 14 bits of space, so if there are ever more than 16383, we
cannot cope.
Currently the code just calles BUG_ON as "all" drivers have request queue
limits much smaller than this.
However is seems that some don't. Apparently some multipath configurations
can allow more than 16383 concurrent write requests.
So, in this unlikely situation, instead of calling BUG_ON we now wait
for the count to drop down a bit. This requires a new wait_queue_head,
some waiting code, and a wakeup call.
Tested by limiting the counter to 20 instead of 16383 (writes go a lot slower
in that case...).

If you lose this race, it can iput a socket inode twice and you get a BUG

cruft to svc_delete_socket so that I could call that function when closing

This was the wrong thing to do. I should have just set SK_CLOSE and let

Not only wrong, but buggy. The locking is all wrong and it openned up a
race where-by a socket could be closed twice.
So this patch:
Introduces svc_close_socket which sets SK_CLOSE then either leave
the close up to a thread, or calls svc_delete_socket if it can
get SK_BUSY.
Adds a bias to sk_busy which is removed when SK_DEAD is set,
This avoid races around shutting down the socket.

So in 'chunk_aligned_read' we check that the bio fits within the parameters

Note that this is the earliest time we can check against the device because

__unmap_hugepage_range() is buggy that it does not preserve dirty state of
huge_pte when unmapping hugepage range. It causes data corruption in the

creates a hugetlb file, modify pages, then unmap it. While leaving the

drop_pagecache_sb() will happily free all pages that aren't marked dirty if
there are no active mapping. Later when application remaps the hugetlb

The PIOE device was left out before because it muxes SDRAM pins (and

It is needed for CompactFlash, however, and now that we have a way
to protect the SDRAM pins, it can be safely added.
