With the introduction of the generic affinity autoselector,
irq_select_affinity(), IRQs are now being retargetted,
using a default mask, via the request_irq() path.
This results in all IRQs targetted at CPU 0.

SN Altix assigns affinity in the SN PROM, and does not
expect that to be changed as part of request_irq().

Set the IRQ_AFFINITY_SET flag to prevent
request_irq() from resetting affinity.

Obvious inclusion of kernel.h doesn't fix it, because of circular dependencies
involving fls.h and log2(). Fixing the latter requires some serious header surgery,
it seems, so just remove BUILD_BUG_ON for now.

This new color expansion acceleration for radeonfb appears to trigger

might be a problem in the VT layer or in X, but I haven't quite found
it yet, so in the meantime, this disables the acceleration by default,

Some systems report SIS 5513 as both vendor/id and subvendor/id
string. In that case we can't distinguish the system by the id
svid/sdid and in fact the entry here breaks some boxes. At some

until then this trades a hang for some users with lower performance

Since applying the fix suggested by the errata (disabling MSI), we've had
issues with interrupts being stuck on despite IIR being 0 on GM965 hardware.
Most reporters of the issue have confirmed that turning MSI back on fixes
things, and given the difficulties experienced in getting reliable MSI working
on Linux, it's believable that the errata was about software issues and not
actual hardware issues.

  Revert "ide: respect current DMA setting during resume"

While 44003728 "[PATCH] switch all filesystems over to
d_obtain_alias" removed some cases where fh_to_dentry() and
fh_to_parent() could return NULL, there are still a few NULL returns
left in individual filesystems.  Thus it was a mistake for that commit
to remove the handling of NULL returns in the callers.

Revert those parts of 44003728 which removed the NULL handling.

(We could, alternatively, modify all implementations to return -ESTALE
instead of NULL, but that proves to require fixing a number of
filesystems, and in some cases it's arguably more natural to return
NULL.)
