True enough, and this problem has been around for some time, and it's
not as simple to fix as "lets just ignore everything else and enable
interrupts to shutup the warning".

There's bigger issues here with syscall restarting that should be
resolved first, and there's work in progress to do that.  Again,
like I said in my previous email, Al's done a great deal of work
in this area and I get the impression that you're redoing some of
that.
