drm/syncobj: add timeline payload query ioctl v6
user mode can query timeline payload. v2: check return value of copy_to_user v3: handle querying entry by entry v4: rebase on new chain container, simplify interface v5: query last signaled timeline point, not last point. v6: add unorder point check Signed-off-by: Chunming Zhou <david1.zhou@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com> Cc: Tobias Hector <Tobias.Hector@amd.com> Cc: Jason Ekstrand <jason@jlekstrand.net> Cc: Dave Airlie <airlied@redhat.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Link: https://patchwork.freedesktop.org/patch/295784/?series=58813&rev=1
