A few prep patches, plus drm/msm conversion to 'struct fence' for gpu and display sync. Uses drm_atomic_helper_wait_for_fences() to sync atomic updates with rendering.
This is the first step towards implementing EGL_ANDROID_native_fence_sync. Next step would be to extend submit uapi to use syncpt fd's (and then eventually somehow plumb through atomic ioctl for fully explicit sync).
Rob Clark (11): reservation: add reservation_object_get_excl_unlocked() drm/atomic: export drm_atomic_helper_wait_for_fences() drm/msm: move debugfs code to it's own file drm/msm: move fence code to it's own file drm/msm: use imported dmabuf's reservation object drm/msm: split out timeout_to_jiffies helper drm/msm/gpu: simplify tracking in-flight bo's drm/msm: split locking and pinning BO's drm/msm: introduce msm_fence_context drm/msm: remove fence_cbs drm/msm: 'struct fence' conversion
