[SPARC]: Add support for *at(), ppoll, and pselect syscalls.
This also includes by necessity _TIF_RESTORE_SIGMASK support, which actually resulted in a lot of cleanups. The sparc signal handling code is quite a mess and I should clean it up some day. Signed-off-by: David S. Miller <davem@davemloft.net>
