fix for stability issues on NV86
Thats all. I have finished the compare process.
Like that or hate that, but in the end the source of so many crashes, data
losses and general suffering,was found to be just one bit,just one bit that
wasn't set by nouveau ctxprog generator in one of ctxvals in per MP state.
(Well my card has 2 MPs, so that would make that 2 bits I guess :-) )
Attached patch was tested by 1/2 hour run of Unegine tropics game.
Unless you have reason to suspect that this bit can break other NV86 cards,
please merge it.
