drm: Remove count_lock for calling lastclose() after
58474713 (v2)
When removing of the BKL the locking around lastclose() was rearranged
and resulted in the holding of the open_count spinlock over the call
into drm_lastclose(). The drivers were not ready for this path to be
atomic - it may indeed involve long waits to release old objects and
cleanup the GPU - and so we ended up scheduling whilst atomic.

This fixes support for PCI domains in what should hopefully be a backward
compatible way along with a change to libdrm.
When the interface version is set to 1.4, we assume userspace understands
domains and the world is at peace. We thus pass proper domain numbers
instead of 0 to userspace.
The newer libdrm will then try 1.4 first, and fallback to 1.1, along with
ignoring domains in the later case (well, except on alpha of course)

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.

Note the impact of this should be slight as on i965 we should be using a
tiled frontbuffer for anything up to a 4096x4096 display.
v2: compilation fixes and note that the docs do not exclude the G35 from
the extra alignment.

drm/i915/pch: Cosmetic fix to FDI link training
Unmask the bits for link training reporting before starting link
training. If stage 1 training finished before we unmask them, then we'd
spin around in a loop a few times until smashing on through. Which is
harmless, since training _did_ succeed, it just looks ugly in dmesg.
