[Mesa-dev] [PATCH] Revert "nouveau: enable use of new kernel interfaces"

[Ilia Mirkin]

This reverts commit a8c474760268f2ebdddd655cea06dbef4500236a, and allows
the new kernel interfaces to be optionally enabled, but still off by
default. Some people are having issues while others aren't, need to
investigate.
