From a0bfa1373859e9d11dc92561a8667588803e42d8 Mon Sep 17 00:00:00 2001 From: Len Brown Date: Fri, 1 Apr 2011 19:34:59 -0400 Subject: cpuidle: stop depending on pm_idle cpuidle users should call cpuidle_call_idle() directly rather than via (pm_idle)() function pointer. Architecture may choose to continue using (pm_idle)(), but cpuidle need not depend on it: my_arch_cpu_idle() ... if(cpuidle_call_idle()) pm_idle(); cc: Kevin Hilman cc: Paul Mundt cc: x86@kernel.org Acked-by: H.
