/* This struct is saved by setup_frame in signal.c, to keep the current context while
   a signal handler is executed. It's restored by sys_sigreturn.
   
   To keep things simple, we use pt_regs here even though normally you just specify
   the list of regs to save. Then we can use copy_from_user on the entire regs instead
   of a bunch of get_user's as well...
