Subject[PATCH][COMPAT] outstanding compatibility changes 1/4 parisc
Hi Linus,

At Linux Conf AU, Willy asked me to send any further parisc compatibility
changes directly to you, so this is what I have outstanding. Basically,
it is just the uses of compat_sigset_t that seemed to have been missed in
the previous merges.
