Right, so I don't see anything wrong with the patch but entry_64.S is
nasty so don't take my word for it.
I guess handlers should need to do "if (user_mode_vm(regs))" after your
change now, in order to know what to do.
I'll try to do some error injection here too, on my boxes to see how
this behaves.
Thanks.
