There is currently a nested function in Russel King's tree
for the msm HDMI driver.
The last nested function was removed from the Linux kernel
when the Thinkpad driver was fixed.
I believe nested functions are not desired upstream, and it
also breaks compilation with clang so here is a patch to
change the nested function into static function. The patch
works with both clang and gcc.

drm/i915: Kill vblank waits after pipe enable on gmch platforms
So it turns out they weren't all entirely useless. Apparently the pipe
has to go through one full frame before we enable the TV port. Add a
vblank wait to intel_enable_tv() to make sure that happens.
Another approach was attempted by placing the vblank wait just after
enabling the port. The theory behind that attempt was that we need to
let the port stay enabled for one full frame before disabling it again
during load detection. But that didn't work, and we definitely must
have the vblank wait before enabling the port.

Running igt, I was encountering the invalid TLB bug on my 845g, despite
that it was using the CS workaround. Examining the w/a buffer in the
error state, showed that the copy from the user batch into the
workaround itself was suffering from the invalid TLB bug (the first
cacheline was broken with the first two words reversed). Time to try a
fresh approach. This extends the workaround to write into each page of
our scratch buffer in order to overflow the TLB and evict the invalid
entries. This could be refined to only do so after we update the GTT,
but for simplicity, we do it before each batch.
I suspect this supersedes our current workaround, but for safety keep
doing both.
v2: The magic number shall be 2.
This doesn't conclusively prove that it is the mythical TLB bug we've
been trying to workaround for so long, that it requires touching a number
of pages to prevent the corruption indicates to me that it is TLB
related, but the corruption (the reversed cacheline) is more subtle than
a TLB bug, where we would expect it to read the wrong page entirely.
Oh well, it prevents a reliable hang for me and so probably for others
as well.

A bunch of warnings fire on some ->irq_postinstall hooks since those
can enable interrupts (e.g. rps interrupts). And then our ordering
self-checks fire and complain.
To fix that set the tracking boolen before enabling the irqs with
drm_irq_install. Quoting the discussion with Jesse why that's safe:

Well we've done it in 4 commits or so, but currently we have:
- Set irqs_disabled to true early in driver load to make sure checks
that. That's done in irq_init, which is totally not the function that
enables interrupts, only the function that initializes all the vtables
and similar things. We actually have a fairly sane naming scheme
nowadays (not fully consistent ofc): _init is sw setup,
_enable/_hw_init is the actual hw setup. That is done in
95f25beddb
- Set irqs_disabled to false right after the irqs are actually
enabled. This is done in ed2e6df189
So my change should only move the flag change over the ->preinstall
and ->postinstall hooks. I've done a little audit and didn't spot
anything amiss. Furthermore the runtime pm setup already clears
irqs_disabled _before_ calling these two hooks.
This regression has been introduced in

drm/i915: clear up wedged transitions
I've accidentally inverted the EIO/wedged handling in the fault

because of the gpu having died, to prevent userspace from unduly
dying.
In my defence the comment right above is completely misleading, so fix
both.

During release of the GEM object we hold the struct_mutex. As the
object may be holding onto the last reference for the task->mm,
calling mmput() may trigger exit_mmap() which close the vma
which will call drm_gem_vm_close() and attempt to reacquire
the struct_mutex. In order to avoid that recursion, we have
to defer the mmput() until after we drop the struct_mutex,
i.e. we need to schedule a worker to do the clean up. A further issue
spotted by Tvrtko was caused when we took a GTT mmapping of a userptr
buffer object. In that case, we would never call mmput as the object
would be cyclically referenced by the GTT mmapping and not freed upon
process exit - keeping the entire process mm alive after the process
task was reaped. The fix employed is to replace the mm_users/mmput()
reference handling to mm_count/mmdrop() for the shared i915_mm_struct.

It is possible that the interface is already gone after joining
the list of anycast on this interface as we don't hold a refcount
for the device, in this case we are safe to ignore the error.
What's more important, for API compatibility we should not
change this behavior for applications even if it were correct.

The example code provided with the i2c device interface documentation
won't compile since it uses the reserved word "register" to name a
variable.
The compiler fails with this error message:
error: expected identifier or '(' before '=' token
__u8 register = 0x20; /* Device register to access */
^
Rename the variable "register" to simply "reg" in the example code.
Another couple of typos has been fixed as well.

Despite the fact that these functions have been around for years, they
are little used (only 15 uses in 13 files at the preseht time) even
though many other files use work-arounds to achieve the same result.
By documenting them, hopefully they will become more widely used.

Commit 0244756edc ("ufs: sb mutex merge + mutex_destroy") introduces
deadlocks in ufs_new_inode() and ufs_free_inode().
Most callers of that functions acqure the mutex by themselves and
ufs_{new,free}_inode() do that via lock_ufs(),
i.e we have an unavoidable double lock.
The patch proposes to resolve the issue by making sure that
ufs_{new,free}_inode() are not called with the mutex held.

Pull xfs fixes from Dave Chinner:
"The fixes all address recently discovered data corruption issues.
The original Direct IO issue was discovered by Chris Mason @ Facebook
on a production workload which mixed buffered reads with direct reads
and writes IO to the same file. The fix for that exposed other issues
with page invalidation (exposed by millions of fsx operations) failing
due to dirty buffers beyond EOF.
Finally, the collapse_range code could also cause problems due to
racing writeback changing the extent map while it was being shifted
around. The commits for that problem are simple mitigation fixes that
prevent the problem from occuring. A more robust fix for 3.18 that
addresses the underlying problem is currently being worked on by
Brian.
Summary of fixes:
- a direct IO read/buffered read data corruption
- the associated fallout from the DIO data corruption fix
- collapse range bugs that are potential data corruption issues"
