[PATCH] alpha smp fix (part #2)
This fixes the bug that caused BUG_ON(!irqs_disabled()) to trigger in run_posix_cpu_timers() on alpha/smp. We didn't disable interrupts properly before calling smp_percpu_timer_interrupt(). We *do* disable interrupts everywhere except this unfortunate smp_percpu_timer_interrupt(). Fixed thus. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
