Each of the change remains fairly trivial but I've split it out by topic. Patches 1, 2 and 3 in this series should be good to go but please don't take patch 4 (which has a small effect on userspace) without an explicit ack from Benjamin Gaignard. I've tested this both with a rather hacked about Android userspace and with a fairly small test case run from debian. Both bits of code currently use dumb buffers. Thanks to Benjamin for his help in finding this bit of code. v2: * Modified DRM_PRIME_HANDLE_TO_FD to honour the O_RDRW from the user and removed code to workaround this from the sti driver (Rob Clark). * Added a patch to (rather spartanly) document gem_prime_mmap. Only tacked into this series 'cos I spotted it was missing when I was checking whether I needed to describe DRM_RDRWR anywhere.
