From 1bac6490fc2e5147abd4b702b172edd6a4dfc077 Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Tue, 29 Nov 2011 16:37:07 -0800 Subject: ARM: idle: call idle notifiers before stopping nohz tick If an idle notifier modifies a timer, calling the notifier after the sched tick has been stopped may leave the sched tick set too early. Move teh idle notifier call before the call to tick_nohz_stop_sched_tick.
