libata: implement and use ATA_QCFLAG_QUIET
Implement ATA_QCFLAG_QUIET which indicates that there's no need to
report if the command fails with AC_ERR_DEV and set it for passthrough
commands.
Combined with previous changes, this now makes device errors for all
direct commands reported directly to the issuer without going through
EH actions and reporting.
Note that EH is still invoked after non-IO device errors to determine
the nature of the error and resume command execution (some controller
requires special care after error to continue). It just performs
default maintenance after error, examines what's going on, realizes
that it's none of its business and reports the command failure without
logging any error messages.

libata: stop being overjealous about non-IO commands
libata EH always revalidated device and retried failed command after

* Make sata_sil24 not request ATA_EH_REVALIDATE on device errors.
sil24 is the only driver which does this. All others let libata EH

* Don't request revalidation after device error of non-IO command.
Revalidation doesn't really help anybody. As ATA_EH_REVALIDATE

sata_promise: ASIC PRD table bug workaround, take 2
Second-generation Promise SATA controllers have an ASIC bug
which can trigger if the last PRD entry is larger than 164 bytes,
resulting in intermittent errors and possible data corruption.
Work around this by replacing calls to ata_qc_prep() with a
private version that fills the PRD, checks the size of the
last entry, and if necessary splits it to avoid the bug.
Also reduce sg_tablesize by 1 to accommodate the new entry.
Tested on the second-generation SATA300 TX4 and SATA300 TX2plus,
and the first-generation PDC20378.
Thanks to Alexander Sabourenkov for verifying the bug by
studying the vendor driver, and for writing the initial patch
upon which this one is based.

This patch will set the correct bits to turn on Aggressive
Link Power Management (ALPM) for the ahci driver. This
will cause the controller and disk to negotiate a lower
power state for the link when there is no activity (see
the AHCI 1.x spec for details). This feature is mutually
exclusive with Hot Plug, so when ALPM is enabled, Hot Plug
is disabled. ALPM will be enabled by default, but it is
settable via the scsi host syfs interface. Possible
settings for this feature are:

Device Initiated Power Management, which is defined
in SATA 2.5 can be enabled for disks which support it.
This patch enables DIPM when the user sets the link
power management policy to "min_power".
Additionally, libata drivers can define a function
(enable_pm) that will perform hardware specific actions to
enable whatever power management policy the user set up
for Host Initiated Power management (HIPM).
This power management policy will be activated after all
disks have been enumerated and intialized. Drivers should
also define disable_pm, which will turn off link power
management, but not change link power management policy.

For the locking to work, only the tag map and tag bit map may be shared

apparently didn't review the code well enough myself). But we also share
the busy list! The busy_list must be queue private, or we need a
block_queue_tag covering lock as well.
So we have to move the busy_list to the queue. This'll work fine, and
it'll actually also fix a problem with blk_queue_invalidate_tags() which
will invalidate tags across all shared queues. This is a bit confusing,
the low level driver should call it for each queue seperately since
otherwise you cannot kill tags on just a single queue for eg a hard
drive that stops responding. Since the function has no callers
currently, it's not an issue.

This patch adds the symbol "init_level4_pgt" to the vmcoreinfo data so
that makedumpfile (dump filtering command) supports x86_64 sparsemem

makedumpfile creates a small dumpfile by excluding unnecessary pages for

necessary pages and unnecessary ones. To check them, makedumpfile gets
the vmcoreinfo data which has the minimum debugging information only for
dump filtering.
For older x86_64 kernel (linux-2.6.23 or before), makedumpfile translates
the virtual address of page structure into physical address by subtracting
PAGE_OFFSET from virtual address, but this translation isn't effective for
linux-2.6.24 sparsemem kernel, because its page structures are in virtual

x86: voyager: fix bogus conversion to per_cpu for boot_cpu_info
There were two problems. Firstly, someone forgot the struct keyword in
front of cpuinfo_x86, so I take it this wasn't even compile checked.
Secondly, the actual definition has this as a SHARED_ALIGNED, so the
definitions mismatch.

mmc_spi: Fix mmc-over-spi regression
mmc: use common byte swap macros
mmc: fix cid and csd byte order
at91_mci: Fix bad reference
This patch fixes that regression by changing the scheme used to keep
from knowingly trying to use a shared bus segment, and updates the
adjacent comments slightly to better explain the issue.
