[Nouveau] [PATCH 0/5][GIT PULL] Miscellaneous fixes for GF100+

[Alexandre Courbot]

Here are a few small fixes for issues we found while implementing
support for GM20B. The first two are specific to Tegra/GK20A, but
the last 3 patches may have a broader (hopefully beneficial) effect.

Note that the newly introduced gf100_gr_wait_idle() function on patch 5/5
is exported on purpose. GK20A and GM20B drivers will soon make use of it.

Ben, since you seemed to like these changes, a pull request follows in
