[PATCH] arm: add cpu_idle tracepoints to arch_cpu_idle

2015-09-16 Thread Jisheng Zhang
Currently, if cpuidle is disabled or not supported, powertop reports zero wakeups and zero events. This is due to the cpu_idle tracepoints are missing. This patch is to make cpu_idle tracepoints always available even if cpuidle is disabled or not supported. Signed-off-by: Jisheng Zhang --- arch
