The "freeze" system sleep state introduced by commit 7e73c5ae6e79 (PM: Introduce suspend state PM_SUSPEND_FREEZE) requires cpuidle to be functional when freeze_enter() is executed to work correctly (that is, to be able to save any more energy than runtime idle), but that is impossible after commit 8651f97bd951d (PM / cpuidle: System resume hang fix with cpuidle) which caused cpuidle to be paused in dpm_suspend_noirq() and resumed in dpm_resume_noirq(). To avoid that problem, add cpuidle_resume() and cpuidle_pause() to the beginning and the end of freeze_enter(), respectively. Reported-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Rafael J.
