Re: [PATCH] paravirt.h

That is a really nasty problem.  You need a synchronization primitive
which guarantees a flat stack, so you can't do it in the interrupt
handler as I have tried to do.  I'll bang my head on it awhile.  In
the meantime, were there ever any solutions to the syscall patching
problem that might lend me a clue as to what to do (or not to do, or
impossible?).

stop_machine_run() solves the problem I think. It is currently not 
exported though. I don't think there's anything in there that couldn't
be reimplemented in a module, but then we could also just export it
if there's a useful user.
