19abe86d60 ixgb: fix TX hangs under heavy load
A merge error occurred where we merged the wrong block here
in version 1.0.120. The right condition for frags is slightly
different then for the skb, so account for the difference properly
and trim the TSO based size right.

Originally part of a fix reported by IBM to fix TSO hangs on
pSeries hardware.

23f42b7b2e serial: fix serial_txx9 console initialization
Since commit 97d97224ff ("[SERIAL] Fix

initialization even if the port was used for console.

This behaviour breaks serial_txx9 console since The serial_txx9 driver
initialize its port entirely on its ->pm() method if new state was 0.
This patch adds checking for oldstate value to fix this probelm.

e027bd36c1 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.

f90f0828e5 libata: stop being overjealous about non-IO commands
libata EH always revalidated device and retried failed command after
error except for ATAPI CCs.  This is unnecessary and hinders with
users issuing direct commands.  This patch makes the following
changes.

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

* Don't request revalidation after device error of non-IO command.
  Revalidation doesn't really help anybody.  As ATA_EH_REVALIDATE
  isn't set by default, there's no reason to clear it after sense data
  is read.  Kill ATA_EH_REVALIDATE clearing code while at it.

* Don't retry non-IO command after device error.  Device has rejected
  the command.  There's no point in retrying.

b666da35d9 libata: flush is an IO command
ATA_QCFLAG_IO is used to mark commands which are used to perform
regluar IO transfers via block layer.  These commands are assumed to
be valid and taken more seriously during error handling.  Cache flush
is used by regular IO path and necessary for data integrity.  Mark it
with ATA_QCFLAG_IO.

b9ccd4a90b 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.

Changes since previous version:

31556594f9 [libata] AHCI: add hw link power management support
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:

Setting         Effect
----------------------------------------------------------
min_power       ALPM is enabled, and link set to enter
                lowest power state (SLUMBER) when idle

ca77329fb7 [libata] Link power management infrastructure
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.

Documentation/scsi/link_power_management_policy.txt has additional
information.

ab6fc95f60 [libata] AHCI: fix newly introduced host-reset bug
The recent fix to host reset introduced a problem, whereby AHCI-enable
bit would be cleared upon reset, if it was not asserted prior to reset.

Unconditionally enable AHCI-enable bit.

db3a91fe2b deal with resource allocation bugs in arcmsr
a) for type B we should _not_ iounmap() acb->pmu; it's not ioremapped.
b) for type B we should iounmap() two regions we _do_ ioremap.
c) if ioremap() fails, we need to bail out (and clean up).

142956af52 fix abuses of ptrdiff_t
Use of ptrdiff_t in places like

-                       if (!access_ok(VERIFY_WRITE, u_tmp->rx_buf, u_tmp->len))
+                       if (!access_ok(VERIFY_WRITE, (u8 __user *)
+                                               (ptrdiff_t) u_tmp->rx_buf,
+                                               u_tmp->len))

is wrong; for one thing, it's a bad C (it's what uintptr_t is for; in general
we are not even promised that ptrdiff_t is large enough to hold a pointer,
just enough to hold a difference between two pointers within the same object).
For another, it confuses the fsck out of sparse.

Use unsigned long or uintptr_t instead.  There are several places misusing
ptrdiff_t; fixed.
