One more time, with feeling..

This series does not include the actual atomic ioctl, but it does include all the needed infrastructure changes.
Compared to previous revision, I've split out drm_modeset_acquire_ctx from drm_atomic_state, so that we can ww acquire mode_config and crtc locks outside of atomic transactions. (Which keeps lockdep happy wrt. drm_modeset_lock_all().) I also got to the point in juggling things around where I wanted to let the compiler type checking do it's job, so 's/void *state/struct drm_atomic_state *state/g'.
At this point, I've tested this on i915 (few different generation laptops), radeon, and msm. And of course w/ ww debug (deadlock in- jection) enabled. So I think all the locking related paths should be covered.
I believe Thierry has tested a slighly older revision on tegra. I would of course appreciate more testing on other drivers for which I don't have the hw. But I think it is pretty much ready to go. I do still owe some docs updates, I will send some patches for that in the near future, but didn't want to hold up giving others a chance to start banging on this.
Rob Clark (14): drm: fix typo drm: add atomic fxns drm: convert crtc and mode_config to ww_mutex drm: add object property type drm: add signed-range property type drm: helpers to find mode objects drm: split propvals out and blob property support drm: allow FB's in drm_mode_object_find drm: convert plane to properties/state drm: convert crtc to properties/state drm: push locking down into restore_fbdev_mode drm/msm: add atomic support drm: spiff out FB refcnting traces drm: more conservative locking
Sean Paul (1): drm: Fix up the atomic legacy paths so they work
Ville Syrjälä (2): drm: Allow drm_mode_object_find() to look up an object of any type drm: Refactor object property check code
