Pull arch signal handling cleanup from Richard Weinberger:
"This patch series moves all remaining archs to the get_signal(),
signal_setup_done() and sigsp() functions.
Currently these archs use open coded variants of the said functions.
Further, unused parameters get removed from get_signal_to_deliver(),
tracehook_signal_handler() and signal_delivered().
At the end of the day we save around 500 lines of code."
