The logic was checking the sizeof the structure being allocated to
determine whether an alignment fixup was required. This isn't right;
what we actually care about is the alignment of the actual pointer that's
about to be returned. This became an issue recently because struct
edac_mc_layer has a size that is not zero modulo eight, so we were
taking the correctly-aligned pointer and forcing it to be misaligned.
On Tile this caused an alignment exception.

Some edac drivers register themselves as mce decoders via
notifier_chain. But in current notifier_chain implementation logic,
it doesn't accept same notifier registered twice. If so, it will be
wrong when adding/removing the element from the list. For example,
on one SandyBridge platform, remove module sb_edac and then trigger
one error, it will hit oops because it has no mce decoder registered
but related notifier_chain still points to an invalid callback
function. Here is an example:

Joe Perches recommended getting rid of the redundant
formatting of adding "PREFIX" to all the uses of pr_*() calls.
The recommendation helps to reduce source and improve
readibility.
While cleaning up the PREFIX's, I saw that one of
the pr_warn() was redundant in dmar_parse_one_dev_scope(),
since the same message was printed after breaking out of the
while loop for the same condition, !pdev.
So, to avoid a duplicate message, I removed the one in the while
loop.

While reworking the r8169 driver a few months ago to perform the
smallest amount of work in the irq handler, I took care of avoiding
any irq mask register operation in the slow work dedicated user
context thread. The slow work thread scheduled an extra round of NAPI
work which would ultimately set the irq mask register as required,
thus keeping such irq mask operations in the NAPI handler.
It would eventually race with the irq handler and delay NAPI execution
for - assuming no further irq - a whole ksoftirqd period. Mildly a
problem for rare link changes or corner case PCI events.
The race was always lost after the last bh disabling lock had been
removed from the work thread and people started wondering where those
pesky "NOHZ: local_softirq_pending 08" messages came from.
Actually the irq mask register _can_ be set up directly in the slow
work thread.

Fix regresson since the introduction of command stream checking on
evergreen (thread referenced below). Issue is cause by ddx allocating
bo with formula width*height*bpp while programming the GPU command
stream with ALIGN(height, 8). In some case (where page alignment does
not hide the extra size bo should be according to height alignment)
the kernel will reject the command stream.
This patch reprogram the command stream to slice - 1 (slice is
a derivative value from height) which avoid rejecting the command
stream while keeping the value of command stream checking from a
security point of view.
This patch also fix wrong computation of layer size for 2D tiled
surface. Which should fix issue when 2D color tiling is enabled.
This dump the radeon KMS_DRIVER_MINOR so userspace can know if

As of edbc454 [mtd: driver _read() returns max_bitflips; mtd_read()
returns -EUCLEAN], 'mtd->bitflip_threshold' must be set for mtd devices
having ECC, prior any 'mtd_read()' call.
Otherwise, 'mtd_read()' will falsely return -EUCLEAN.
Normally, 'mtd->bitflip_threshold' is initialized when the MTD is added.
However, this is too late for NAND MTDs, as 'scan_bbt()' is invoked
prior the existing initialization of 'mtd->bitflip_threshold'.
This is a problem since 'scan_bbt()' calls 'mtd_read()', in the case
of a flash-based bad block table.
It resulted in a falsely reported bitflips indication during BBT read,
which lead to constant scrubbing of the flash BBT blocks.
Initialize 'mtd->bitflip_threshold' to its default value (if not already
set by the driver), prior to invocation of 'scan_bbt()'.

This reverts commit 9e612a008fa7fe493a473454def56aa321479495.
It incorrectly finds VGA connectors where none are attached, apparently
not noticing that nothing replied to the EDID queries, and happily using
the default EDID modes that have nothing to do with actual hardware.
That in turn then causes X to fall down to the lowest common
denominator, which is usually the default 1024x768 mode that is in the
default EDID and pretty much anything supports).
I'd suggest that if not relying on the HDP pin, the code should at least
check whether it gets valid EDID data back, rather than just assume
there's something on the VGA connector.

When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.
This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.
The message is the log that was printed is:
Queue 2 stuck for 10000ms
This doesn't seem to fix the higher queues that get stuck
from time to time.

Removing _sync is ok, because if led_on work is currently running
it will be finished before led_off work start to perform, since
they are always queued on the same mac80211 local->workqueue.

This warning appears only if we apply Ben Hutchings' fix
http://marc.info/?l=linux-wireless&m=132720204412667&w=2
for the bug reported by Cesare Leonardi
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=656813
with cfg80211 warning during device registration
("cfg80211: failed to add phy80211 symlink to netdev!").
We separate device bring up and registration with network stack
to avoid the problem.

Pull in AMD MCE thresholding fixes for v3.6, from Borislav Petkov:
" Those are a bunch of patches which give the MCE thresholding code a
hard look and a scrubbing to remove a couple of annoyances like sysfs
warnings when running CPU off-/online tests and the threshold_bank4 node
under /sys/devices/system/machinecheck/ is a symlink.
It also gives proper names to the thresholding banks instead of simply
enumerating them, like this:
/sys/devices/system/machinecheck/machinecheck0/
