From: Viresh Kumar <viresh.kumar@xxxxxxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 27630532ef5ead28b98cfe28d8f95222ef91c2b7 upstream. Since commit d689fe222 (NOHZ: Check for nohz active instead of nohz enabled) the tick_nohz_switch_to_nohz() function returns because it checks for the tick_nohz_active flag. This can't be set, because the function itself sets it. Undo the change in tick_nohz_switch_to_nohz().
