From: Ivan Kokshaysky Date: Fri, 1 Jul 2005 12:46:26 +0000 (+0400) Subject: [PATCH] alpha smp fix (part #2) X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4a89a04f1ee21a7c1f4413f1ad7dcfac50ff9b63;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [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.
