[Nouveau] [PATCH v2 0/3] ARB_viewport_array for nvc0
This patch-series implements the ARB_viewport_array for nvc0 and does a little house-cleanig afterwords.

[Nouveau] [PATCH v2 1/3] nvc0: implement multiple viewports/scissors, enable ARB_viewport_array
I've made a few small fixes to this -- you forget to set the scissors/viewports dirty to ~0 on context switch, and also marking the first scissor dirty after a 3d blit (which I was forgetting to do on nv50 as well... oops). I'll push this out shortly with my modifications.
