/* 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...
