Commit drm/ttm: ttm object security fixes for render nodes introduced a
regression where, if a TTM object was opened multiple times from the same
open file, the caller would spin uninterruptibly in the kernel.
Fix this.

Summary:
- GK110/GK208 acceleration
- loads more work towards pm, though, still behind a disable wall for now
- error reporting improvements from both Ilia and myself
- more old-school overlay improvements from Ilia
- misc other bits and pieces
* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (68 commits)
drm/nouveau: call drm_vblank_cleanup() earlier
drm/nouveau: create base display from common code
drm/nv50/gr: print mpc trap name when it's not an mp trap
drm/nv50/gr: update list of mp errors, make it a bitfield
drm/nv50/gr: add more trap names to print on error
drm/nouveau/devinit: lock/unlock crtc regs for all devices, not just pre-nv50
drm/nouveau: hold mutex while syncing to kernel channel
drm/nv50-/devinit: prevent use of engines marked as disabled by hw/vbios
drm/nouveau/device: provide a way for devinit to mark engines as disabled
drm/nouveau/devinit: tidy up the subdev class definition
drm/nouveau/bar: tidy up the subdev and object class definitions
drm/nouveau/instmem: tidy up the object class definition
drm/nouveau/instmem: tidy up the subdev class definition
drm/nouveau/pwr: implement a simple i2c stack
drm/nouveau/pwr: have rd/wr32 routines clobber data instead of addr
drm/nve0/fb: turn off some bits in 10f584 at init
drm/nve0/fb/gddr5: merge a fix from ddr3 for one of the timing settings
drm/nve0/fb/gddr5: yet another random 10f200 bit
drm/nvc0-/fb: hook up skeleton interrupt handler
drm/nve0/fb/gddr5: more 10f200 stuff
...
Also make nv_lockvgac work for nv50+ devices. This should fix
IO_CONDITION and related VBIOS opcodes that read/write the crtc regs.

Not holding the mutex potentially causes corruption of the kernel
channel when page flipping.

Seen on Titan. NFI what the condition to switch this on is yet, and,
hardcoding it to on currently causes master to report unknown intr
with a mask of 0x08002000.

Still essentially a struct of magic values with magic names and unknown
purposes. But, we will shortly need to be able to mix and match bits of
the previous and next configurations to do a transition reclock, as such,
we can no longer directly use the vbios data with any ease.
This is probably nicer anyway in the long run, for a few reasons.
