[PATCH] drm: reorder drm_open_hash to remove padding on 64 bit builds

Remove 8 bytes of padding on 64 bit builds to reduce the size of drm_open_hash to 24 bytes, which also shrinks drm_object_file by 24 bytes (136 -> 112) allowing it to fit in one fewer cache lines and a smaller slab.

Signed-off-by: Richard Kennedy richard@rsk.demon.co.uk --- patch against v2.6.38-rc6 compiled & tested on x86_64 with nouveau.

regards Richard
