drm/msm: Add hint to DRM_IOCTL_MSM_GEM_INFO to return an object IOVA
Modify the 'pad' member of struct drm_msm_gem_info to 'flags'. If the user sets 'flags' to non-zero it means that they want a IOVA for the GEM object instead of a mmap() offset. Return the iova in the 'offset' member. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> [robclark: s/hint/flags in commit msg] Signed-off-by: Rob Clark <robdclark@gmail.com>
