From faad38492814112e3e7ce94d90123bbe301fff33 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 10 May 2015 01:18:03 +0200 Subject: sched / idle: Call idle_set_state() from cpuidle_enter_state() Introduce a wrapper function around idle_set_state() called sched_idle_set_state() that will pass this_rq() to it as the first argument and make cpuidle_enter_state() call the new function before and after entering the target state. At the same time, remove direct invocations of idle_set_state() from call_cpuidle(). This will allow the invocation of default_idle_call() to be moved from call_cpuidle() to cpuidle_enter_state() safely and call_cpuidle() to be simplified a bit as a result. Signed-off-by: Rafael J.
