[Mesa-dev] [v2] Meta path for gen8 stencil

[Topi Pohjolainen]

In addition to first version there is now also path for miptree
updownsampling. While the relevant piglit tests don't crash on BDW
anymore, they do not pass either - it seems that there are still SRGB
blits needed that on previous hardware are covered by blorp. Using
the stencil texturing support on IVB I was able to check that the new
stencil updownsampling logic does not regress these tests.

Topi Pohjolainen (8):
  i965/wm: Surface state overrides for configuring w-tiled as y-tiled
  i965/gen8: Surface state overriding for stencil
  i965: Extend brw_get_rb_for_first_slice() for specified level/layer
  meta: Refactor state save/restore for framebuffer texture blits
  i965/meta: Stencil blits
  i965/fb: Use meta path for stencil blits
  i965/meta: Stencil blit for miptree updownsampling
  i965/fb: Use meta path for stencil up/downsampling
