[PATCH 0/9] drm/nouveau: Cleanup event/handler design
This series was originally motivated by a deadlock, introduced in
commit 1d7c71a3e2f77336df536855b0efd2dc5bdeb41b
'drm/nouveau/disp: port vblank handling to event interface',
due to inverted lock order between nouveau_drm_vblank_enable()
and nouveau_drm_vblank_handler() (the complete
lockdep report is included in the patch 4/5 changelog).
Because this series fixes the vblank event

[RFC PATCH v1 00/16] Convert all ttm drivers to use the new reservation interface
This series depends on the previously posted reservation api patches.
2 of them are not yet in for-next-fences branch of
git://git.linaro.org/people/sumit.semwal/linux-3.x.git
The missing patches are still in my vmwgfx_wip branch at
git://people.freedesktop.org/~mlankhorst/linux
All ttm drivers are converted to the fence api, fence_lock is removed
and rcu is used in its place.
qxl is the first

[PATCH 00/17] Convert TTM to the new fence interface.
This series applies on top of the driver-core-next branch of
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git
Before converting ttm to the new fence interface I had to fix some
drivers to require a reservation before poking with fence_obj.
After flipping the switch RCU becomes available instead, and
the extra reservations can be dropped again. :-)
I've done at least basic
