[Intel-gfx] [PATCH v2 00/15] drm/i915: Cursor code cleanup and cursor "FBC" support for IVB+ (v2)

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Another iteration of my cursor stuff. I ended up expanding it quite a bit
because I decided that I need to handle the fb/src offsets correctly.

I also tried to address some of Chris's review feedback, mainly about
sharing some of the code between the i9xx and i845/i865 codepaths.

The mess with the conditional register writes was also starting to
bother me, so I tried to make it less convoluted, but spliting it
between just updating CURPOS vs. updating everything. This even seemed
improve the performance a little bit on my old 830.
