Ok, I've suppressed some trailing spaces and changed the commit message.

Subject: [PATCH 1/1] gallium: Implements the new meaning of PIPE_BIND_SHARED
(there should be no tiling) for i915, ilo, nv50, nvc0, r300, r600, radeonsi.
intel: _DRI_IMAGE_USE_SHARE is equivalent to PIPE_BIND_SHARED. No tiling
either for the dri drivers i915 and i965.
