IA64: Optimize ticket spinlocks in fsys_rt_sigprocmask
commit 2d2b6901649a62977452be85df53eda2412def24 upstream.
Tony's fix (f574c843191728d9407b766a027f779dcd27b272) has a small bug,
it incorrectly uses "r3" as a scratch register in the first of the two
unlock paths ... it is also inefficient. Optimize the fast path again.
