Christ. It's been two weeks. I'm doing -rc4 today, and I still don't
have the fix.
The problem seems entirely obvious, as reported by Kirill: the nv50
code unconditionally calls the "atomic_{dis,en}able()" functions, even
when not everybody was converted.
The fix seems to be to either just do the conversion of the remaining
cases (which looks like just adding an argument to the remaining
functions, and using that for the "atomic" callback), or the trivial
suggestion by Kirill from two weeks ago:

Kirill, since the nouveau people aren't fixing this, can you just send
me your tested patch?
Lyude/Ben - let me just say that I think this is all a huge disgrace.
You had a problem report with a bisected commit, a suggested fix, and
two weeks later there's absolutely _nothing_.
