Upon deeper review it was agreed to remove the driver-unique
'locality' sysfs attribute before it is present in a released
kernel.
The attribute was introduced in e2683957fb
during the 3.12 merge window, so this patch needs to go in before
3.12 is released.
The hope is to have a well defined locality API that all the other
locality aware drivers can use, perhaps in 3.13.

drm/i915: set up PIPECONF explicitly for i9xx/vlv platforms
Ville brough up the idea that this is just the pipe A quirk gone
wrong.
Note that after resume the bios might or might not have enabled pipe A
already. We have a bit of magic to make sure that on resume we set up
a decent mode for pipe A, but I fear if I just smash pipe A to always
on we'd enable it in a bogus state and hang the hw. Hence the
readback.
v2: Clarify the logic a bit as suggested by Chris. Also amend the
commit message to clarify why we don't unconditionally enable the
pipe.

The native TV encoder has it's own flags to adjust sync modes and
enabled interlaced modes which are totally irrelevant for the adjusted
mode. This worked out nicely since the input modes used by both the
load detect code and reported in the ->get_modes callbacks all have no
flags set, and we also don't fill out any of them in the ->get_config
callback.
This changed with the additional sanitation done with
commit 2960bc9cce

drm/i915: make user mode sync polarity setting explicit
sinc now the "no flags at all" state wouldn't fit through core code
any more. So fix this up again by explicitly clearing the flags in the
->compute_config callback.
Aside: We have zero checking in place to make sure that the requested
mode is indeed the right input mode we want for the selected TV mode.
So we'll happily fall over if userspace tries to pull us. But that's
definitely work for a different patch series. So just add a FIXME
comment for now.

the moderately detailed cache control and the open coding of a register

After a fair number of xfstests runs, xfs/182 started to fail
regularly with a corrupted directory - a directory read verifier was
failing after recovery because it found a block with a XARM magic
number (remote attribute block) rather than a directory data block.
The first time I saw this repeated failure I did /something/ and the
problem went away, so I was never able to find the underlying
problem. Test xfs/182 failed again today, and I found the root
cause before I did /something else/ that made it go away.
Tracing indicated that the block in question was being correctly
logged, the log was being flushed by sync, but the buffer was not
being written back before the shutdown occurred. Tracing also
indicated that log recovery was also reading the block, but then
never writing it before log recovery invalidated the cache,
indicating that it was not modified by log recovery.
More detailed analysis of the corpse indicated that the filesystem
had a uuid of "a4131074-1872-4cac-9323-2229adbcb886" but the XARM
block had a uuid of "8f32f043-c3c9-e7f8-f947-4e7f989c05d3", which
indicated it was a block from an older filesystem. The reason that
log recovery didn't replay it was that the LSN in the XARM block was
larger than the LSN of the transaction being replayed, and so the
block was not overwritten by log recovery.
Hence, log recovery cant blindly trust the magic number and LSN in
the block - it must verify that it belongs to the filesystem being
recovered before using the LSN. i.e. if the UUIDs don't match, we
need to unconditionally recovery the change held in the log.
This patch was first tested on a block device that was repeatedly
causing xfs/182 to fail with the same failure on the same block with
the same directory read corruption signature (i.e. XARM block). It
did not fail, and hasn't failed since.

When we free an inode, we do so via RCU. As an RCU lookup can occur
at any time before we free an inode, and that lookup takes the inode
flags lock, we cannot safely assert that the flags lock is not held
just before marking it dead and running call_rcu() to free the
inode.
We check on allocation of a new inode structre that the lock is not
held, so we still have protection against locks being leaked and
hence not correctly initialised when allocated out of the slab.
Hence just remove the assert...
