[Intel-gfx] [PATCH 00/11] drm/i915: Patches cherry-picked from drm_atomic

[ville.syrjala at linux.intel.com]

Here's a bunch of changes that were sitting in my drm_atomic tree, but
not really related to that work.

I quickly modified the fb offset handling patch to avoid having to
write test cases :), and the stride patch to avoid open questions
about <=Gen4 stride limits.

The execbuffer patch is an open question because IIRC Chris said
he doesn't like the whole concept. So if we don't want that patch,
then I think we should either remove the whole mechanism, or at least
disable it on IVB. Currently it seems capable of adding MI_WAIT_EVENT
commands into the ring with undefined wait bits enabled.
