drm/radeon: Add RADEON_INFO_VA_UNMAP_WORKING query
This tells userspace that it's safe to use the RADEON_VA_UNMAP operation of the DRM_RADEON_GEM_VA ioctl. Cc: stable@vger.kernel.org (NOTE: Backporting this commit requires at least backports of commits 26d4d129b6042197b4cbc8341c0618f99231af2f, 48afbd70ac7b6aa62e8d452091023941d8085f8a and c29c0876ec05d51a93508a39b90b92c29ba6423d as well, otherwise using RADEON_VA_UNMAP runs into trouble) Signed-off-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com>
