When ide taskfile access is being used (for example with hdparm --security
commands) and cfq scheduler is selected, the scheduler crashes on BUG in
cfq_put_request.
The reason is that the cfq scheduler is tracking counts of read and write
requests separately; the ide-taskfile subsystem allocates a read request and
then flips the flag to make it a write request. The counters in cfq will
mismatch.
This patch changes ide-taskfile to allocate the READ or WRITE request as
required and don't change the flag later.

NODEMASK_ALLOC/FREE are mapped to kmalloc/free if NODES_SHIFT > 8.
Among its several users, drivers/base/node.c wasn't including slab.h
leading to build failure if NODES_SHIFT > 8. Include slab.h from
drivers/base/node.c.
This isn't an ideal solution but including slab.h directly from
nodemask.h is not an option because nodemask.h gets included
everywhere. For now, make it work by including slab.h from its users.

There is a problem with the ACPI video resume routine that it's
executed before the GPU that may be accessed by it. To fix this
issue, move the ACPI video resume to a power management notifier,
so that's executed after resuming all devices, including the GPU.
Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15096, which is
a listed regression from 2.6.31.

Some BIOSes don't configure HPA during boot but do so while resuming.
This causes harddrives to shrink during resume making libata detach
and reattach them. This can be worked around by unlocking HPA if old
size equals native size.
Add ATA_DFLAG_UNLOCK_HPA so that HPA unlocking can be controlled
per-device and update ata_dev_revalidate() such that it sets
ATA_DFLAG_UNLOCK_HPA and fails with -EIO when the above condition is
detected.
This patch fixes the following bug.

Crucial said,
Thank you for contacting us. We know that with our M225 line of SSDs
you sometimes need to disable NCQ (native command queuing) to avoid
just the type of errors you're seeing. Our recommendation for the
M225 is to add libata.force=noncq to your Linux kernel boot options,
under the kernel ATA library option.
I have sent your feedback to the engineers working on the C300, and
asked them to please pass it on to the firmware team. I have been
notified that they are in the process of testing and finalizing a
new firmware version, that you can expect to see released around the
end of April. We’ll keep you posted as to when it will be available
for download.
So, turn off NCQ on the drive w/ the current firmware revision.

In an embedded system the matrix_keypad driver might be used to
interface with an external control panel and not an actual keyboard.
On the control panel some of the keys could be used to turn on/off
various functions. If key autorepeat is enabled this causes the
function to quickly toggle between the on and off states and makes
operation difficult.
Add an option in the platform-specific data to disable the key
autorepeat.

By default, ACPI resource conflict messages are logged at level
KERN_ERR. This is a rather high level for a message that is more a
warning than an indication of a real kernel error. Also, KERN_ERR level
messages can appear over some boot splash screens, and this message is
not serious enough to warrant such treatment. Thus, the log level has
been reduced to KERN_WARNING.
[lenb changed to KERN_WARNING rather than all the way to KERN_INFO]
Also, cleanup message to use %pR resource printing format.

- pcmcia_align() used a "start" variable twice. That's obviously a bad
idea.
- pcmcia_common_resource() needs the current "start" parameter being
passed, instead of res->start.
- pcmcia_common_resource() doesn't use the size and align parameters,
so get rid of those.

The ACPI spec (sec 6.4.3.5 in v4.0) requires that for Address Space Resource
Descriptors, _LEN <= _MAX - _MIN + 1 in all cases, but there are BIOSes that
violate this. We experimentally determined that Windows truncates the
resource so it doesn't extend past _MAX, so let's do the same thing in
Linux.

Previously, we assumed the only Device object immediately below the root
was the \_SB Scope (which the ACPI CA treats as a Device), so we forced
the HID of all such objects to ACPI_BUS_HID ("LNXSYBUS").
However, there are DSDTs that supply root-level Device objects with _HIDs.
This patch makes us pay attention to those _HIDs and only add the synthetic
ACPI_BUS_HID for root-level objects that do not supply their own _HID.
For example, this DSDT: https://bugzilla.kernel.org/show_bug.cgi?id=15605
contains:
Scope (_SB) {
...
}
Device (AMW0) {
Name (_HID, EisaId ("PNP0C14"))
...
}
and we should use "PNP0C14" for the AMW0 device, not "LNXSYBUS".

We used to free all the Tx queues memory when interface is brought
down and reallocate them again in interface up. This requires
order-4 allocation for txq->cmd[]. In situations like s2ram, this
usually leads to allocation failure in the memory subsystem. The
patch fixed this problem by allocating the Tx queues memory only at
the first time. Later iwl_down/iwl_up only initialize but don't
free and reallocate them. The memory is freed at the device removal
time. BTW, we have already done this for the Rx queue.
