I'd rather get something explicitly tested. I tried my earlier patch
with "make allmodconfig" (and a fix to nfsd to make it compile), but
now I'm back to testing hjl's gas updates so it would be better to get
a tested commit with a good commit message.

Oh, I think Maciej needs to get more than a "Reported-by:". This was a
really subtle thing that we didn't figure out in the original thread,
so give him a gold star in the form of "Root-caused-by:" or something.

*Fixing* this ends up being a one-liner or so. Finding the cause was
the painful part.
