ae01b2493c (libata: Implement ATA_FLAG_NO_DIPM and apply it to mcp65)
added ATA_FLAG_NO_DIPM and made ata_eh_set_lpm() check the flag.
However, @ap is NULL if @link points to a PMP link and thus the
unconditional @ap->flags dereference leads to the following oops.

Fix it by testing @link->ap->flags instead.
stable: ATA_FLAG_NO_DIPM was added during 2.6.39 cycle but was
backported to 2.6.37 and 38. This is a fix for that and thus
also applicable to 2.6.37 and 38.

This reverts commit 270dac35c26433d06a89150c51e75ca0181ca7e4.
The commits causes command timeouts on AC plug/unplug. It isn't yet
clear why. As the commit was for a single rather obscure controller,
revert the change for now.
The problem was reported and bisected by Gu Rui in bug#34692.

This moves the
if (num_registered_fb == FB_MAX)
return -ENXIO;
check _AFTER_ the call to do_remove_conflicting_framebuffers() as this
would (now in a safe way) allow a native driver to replace the
conflicting one even if all slots in registered_fb[] are taken.
This also prevents unregistering a framebuffer that is no longer
registered (vga16f will unregister at module unload time even if the
frame buffer had been unregistered earlier due to being found
conflicting).

When a register_framebuffer() call results in us removing old
conflicting framebuffers, the new registration_lock doesn't protect that
situation. And we can't just add the same locking to the function,
because these functions call each other: register_framebuffer() calls
remove_conflicting_framebuffers, which in turn calls
unregister_framebuffer for any conflicting entry.
In order to fix it, this just creates wrapper functions around all three
functions and makes the versions that actually do the work be called
"do_xxx()", leaving just the wrapper that gets the lock and calls the
worker function.
So the rule becomes simply that "do_xxxx()" has to be called with the
lock held, and now do_register_framebuffer() can just call
do_remove_conflicting_framebuffers(), and that in turn can call
_do_unregister_framebuffer(), and there is no deadlock, and we can hold
the registration lock over the whole sequence, fixing the races.
It also makes error cases simpler, and fixes one situation where we
would return from unregister_framebuffer() without releasing the lock,
pointed out by Bruno Prémont.

The rbd driver currently splits bios when they span an object boundary.
However, the blk_end_request expects the completions to roll up the results
in block device order, and the split rbd/ceph ops can complete in any
order. This patch adds a struct rbd_req_coll to track completion of split
requests and ensures that the results are passed back up to the block layer
in order.
This fixes errors where the file system gets completion of a read operation
that spans an object boundary before the data has actually arrived. The
bug is easily reproduced with iozone with a working set larger than
available RAM.

My Q67 / i7-2600 box has rev09 Sandy Bridge graphics. It hangs
instantly when GNOME loads and it hangs so hard the reset button
doesn't work. Setting i915.semaphore=0 fixes it.
Semaphores were disabled in a1656b9090f7 ("drm/i915: Disable GPU
semaphores by default") in 2.6.38 but were then re-enabled (by mistake?)
by the merge 47ae63e0c2e5 ("Merge branch 'drm-intel-fixes' into
drm-intel-next").
(It's worth noting that the offending change is i915_drv.c, which was
not marked as a conflict - although a 'git show --cc' on the merge does
show that neither parent had it set to 1)

With some combinations of arch/compiler (e.g. arm-linux-gcc) the sizeof
operator on structure returns value greater than expected. In cases when the
structure is used for mapping PDU fields it may lead to unexpected results
(such as holes and alignment problems in skb data). __packed prevents this
undesired behavior.

Quoth Franz Melchior:
"This patch introduces a bug on my infamous "Acer Travelmate
5735Z-452G32Mnss": when KMS takes over, the frame buffer contents get
completely garbled up on screen, with colored stripes and unreadable
text (photo on request). Only when X11 is started, the screen gets
restored again. Closing and re-opening the lid partly cures the
mess, too: it makes the font readable, though horizontally stretched."

read/write/ioctl on a fbcon file descriptor has traditionally used the
fbcon not when it was opened, but as it was at the time of the call.
That makes no sense, but the lack of sense is much more obvious now that
we properly ref-count the usage - it means that the ref-counting doesn't
actually protect operations we do on the frame buffer.
This changes it to look at the fb_info that we got at open time, but in
order to avoid using a frame buffer long after it has been unregistered,
we do verify that it is still current, and return -ENODEV if not.

This just adds the refcount and the new registration lock logic. It
does not (for example) actually change the read/write/ioctl routines to
actually use the frame buffer that was opened: those function still end
up alway susing whatever the current frame buffer is at the time of the
call.
Without this, if something holds the frame buffer open over a
framebuffer switch, the close() operation after the switch will access a
fb_info that has been free'd by the unregistering of the old frame
buffer.
(The read/write/ioctl operations will normally not cause problems,
because they will - illogically - pick up the new fbcon instead. But a
switch that happens just as one of those is going on might see problems
too, the window is just much smaller: one individual op rather than the
whole open-close sequence.)
This use-after-free is apparently fairly easily triggered by the Ubuntu
11.04 boot sequence.

We enabled write-combining for memory-mapped registers in commit
65f0b417dee94f779ce9b77102b7d73c93723b39, but inhibited it for the
MCDI shared memory where this is not supported. However,
write-combining mappings also allow read-reordering, which may also
be a problem.
I found that when an SFC9000-family controller is connected to an
Intel 3000 chipset, and write-combining is enabled, the controller
stops responding to PCIe read requests during driver initialisation
while the driver is polling for completion of an MCDI command. This
results in an NMI and system hang. Adding read memory barriers
between all reads to the shared memory area appears to reduce but not
eliminate the probability of this.
We have not yet established whether this is a bug in our BIU or in the
PCIe bridge. For now, work around by mapping the shared memory area
separately.

With commit 19403165 a main part of ehci-omap.c moved to
drivers/mfd/omap-usb-host.c created by commit 17cdd29d.
Due to this reorganisation the polarity used to reset the
external USB phy changed and USB host doesn't recognize
any devices.

The Xen changes were using DMA_ERROR_CODE which isn't defined on a few
platforms, however we reverted the Xen patch that caused use to try and
use this code path earlier in 2.6.39 cycle, so for now lets just force
the code to never take this path and allow it to build again on alpha.
The proper long term answer is probably to store if the dma_addr has
been assigned to alongside the dma_addr in the higher level code,
though I think Thomas wanted to rewrite most of this anyways properly.

We occasionally see list corruption using libertas.
While we haven't been able to diagnose this precisely, we have spotted
a possible cause: cmdpendingq is generally modified with driver_lock
held. However, there are a couple of points where this is not the case.
Fix up those operations to execute under the lock, it seems like
the correct thing to do and will hopefully improve the situation.

We should not switch to non-IBSS channels when working in IBSS mode,
otherwise there are microcode errors, and after some time system
crashes.
This bug is only observable when software scan is used in IBSS mode,
so should be considered as regression after:
commit 0263aa45293838b514b8af674a03faf040991a90
Author: Stanislaw Gruszka <sgruszka@redhat.com>

iwl3945: disable hw scan by default
However IBSS mode check, which this patch add again, was removed by
commit b2f30e8bdd8ef5f3b5a7ef9146509585a15347d3
Author: Johannes Berg <johannes.berg@intel.com>

iwlwifi: remove IBSS channel sanity check
That commit claim that mac80211 will not use non-IBSS channel in IBSS
mode, what definitely is not true. Bug probably should be fixed in
mac80211, but that will require more work, so better to apply that patch
temporally, and provide proper mac80211 fix latter.

during suspend/S3 state drv_flush is called from mac80211 irrespective of
interface count. In ath9k we queue a work in ath9k_flush which we expect
to be cancelled in the drv_stop call back. during suspend process mac80211
calls drv_stop only when the interface count(local->count) is non-zero.
unfortunately when the network manager is enabled, drv_flush is called
while drv_stop is not called as local->count reaches '0'.
So fix this by simply checking for the device presence in the
drv_flush call back in the driver before queueing work or anything else.
this patch fixes the following WARNING
