Previously we just allocated space for four hardware semaphores in each software semaphore object. Make software semaphore objects represent only one hardware semaphore address again by splitting the sync code into it's own object. v2: fix typo in comment Signed-off-by: NChristian König <christian.koenig@amd.com> Signed-off-by: NAlex Deucher <alexander.deucher@amd.com>

Semaphore values have 64 bits, not 32. This fixes a very subtle bug that disables synchronization when the upper 32bits wasn't zero.

The CP semaphore queue on CIK has a bug that triggers if uncompleted waits use the same address while a signal is still pending. Work around this by using different addresses for each sync.

Remove redundant DRM UAPI header #inclusions from drivers/gpu/. Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding patch. Without this patch and the patch to make include the UAPI headers from the core headers, after the UAPI split, the DRM C sources cannot find these UAPI headers because the DRM code relies on specific -I flags to make #include "..." work on headers in include/drm/ - but that does not work after the UAPI split without adding more -I flags.
