This patchset tries to go towards implementing both virtio-1 compliant and transitional virtio drivers in Linux. Branch available at git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux virtio-1 This is based on some old patches by Rusty to handle extended feature bits and endianness conversions. Thomas implemented the new virtio-ccw transport revision command, and I hacked up some

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

fence_is_signaled callback should support being run in atomic context, but not in irq context.

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
