drm/nouveau: fix race condition when under memory pressure
When VRAM is running out it's possible that the client's push buffers get
evicted to main memory. When they're validated back in, the GPU may
be used for the copy back to VRAM, but the existing synchronisation code
only deals with inter-channel sync, not sync between PFIFO and PGRAPH on
the same channel. This leads to PFIFO fetching from command buffers that
haven't quite been copied by PGRAPH yet.
This patch marks push buffers as so, and forces any GPU-assisted buffer
moves to be done on a different channel, which triggers the correct
synchronisation to happen before we submit them.

drm: kill BKL from common code
This restricts the use of the big kernel lock to the i830 and i810
device drivers. The three remaining users in common code (open, ioctl
and release) get converted to a new mutex, the drm_global_mutex,
making the locking stricter than the big kernel lock.
This may have a performance impact, but only in those cases that
currently don't use DRM_UNLOCKED flag in the ioctl list and would
benefit from that anyway.
The reason why i810 and i830 cannot use drm_global_mutex in their
mmap functions is a lock-order inversion problem between the current
use of the BKL and mmap_sem in these drivers. Since the BKL has
release-on-sleep semantics, it's harmless but it would cause trouble
if we replace the BKL with a mutex.
Instead, these drivers get their own ioctl wrappers that take the
BKL around every ioctl call and then set their own handlers as
DRM_UNLOCKED.

drm/i915: Attempt to uncouple object after catastrophic failure in unbind
If we fail to flush outstanding GPU writes but return the memory to the
system, we risk corrupting memory should the GPU recovery and complete
those writes. On the other hand, if we bail early and free the object
then we have a definite use-after-free and real memory corruption.
Choose the lesser of two evils, since in order to recover from the hung
GPU we need to completely reset it, those pending writes should
never happen.

drm/i915: Repeat unbinding during free if interrupted (v6)
If during the freeing of an object the unbind is interrupted by a system
call, which is quite possible if we have outstanding GPU writes that
must be flushed, the unbind is silently aborted. This still leaves the
AGP region and backing pages allocated, and perhaps more importantly,
the object remains upon the various lists exposing us to memory
corruption.
I think this is the cause behind the use-after-free, such as

We cannot simply spin to clear the pending signal and so must deferred
the freeing of the object until later.

The original i965, including the revised G35 and Q35, requires an

increase the requirement from 64k for these chipsets. For the later
chipsets in the i965 family, only a 4k alignment is required. (So
long as we do not start performing asynchronous flips.)
