[PATCH 0/3] fb fixes for gk20a/gm20b
...ch "fb/gf100: defer DMA
mapping of scratch page to oneinit() hook" was applied, I noticed that moving
the 100c10 page allocation to the oneinit() hook resulted in that page being
now allocated for Tegra as well, and accesses be made to members of gf100_fb
which were not accessible because gk20a_fb_new() called nvkm_fb_new_() directly.
This is fixed by patch 1, but looking at this code made me realize we may just
as well use the regular FB functions for gk20a/gm20b (without the ablity to
allocate VRAM of course), so patches 2 and 3 do that.
