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/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.

drm: Free the idr layers before calling idr_destroy()
/* A typical clean-up sequence for objects stored in an idr tree, will

We were missing the vital idr_rmove_all() step and so were leaking
the used layers for every dri client:

drm/nouveau: set TASK_(UN)INTERRUPTIBLE before schedule_timeout()
set_current_state() is called only once before the first iteration.
After return from schedule_timeout() current state is TASK_RUNNING. If
we are going to wait again, set_current_state() must be called.

drm/radeon/kms: remove rs4xx gart limit
We used to limit the rs4xx gart aperture to 32 MB, but I suspect
that was due to not meeting the alignment requirements of the
aperture. This patch should only be applied after:
"drm/radeon/kms: fix gtt MC base alignment on rs4xx/rs690/rs740 asics"
has been applied.
This patch should probably soak for a bit in d-r-t.

drm: radeon: fix sign bug
The "error" variable is unsigned so it's never less than zero. I
changed it to check if (freq < current_freq) directly.
"best_error" is also unsigned so "best_error - 100" could be a large
number instead of a negative. Since "error" is unsigned it is never
less than a negative and so the cases where "best_error" is less than or
equal to 100 are false.
