[IA64] Optimize ticket spinlocks in fsys_rt_sigprocmask 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. Signed-off-by: Petr Tesarik <ptesarik@suse.cz> Signed-off-by: Tony Luck <tony.luck@intel.com>
