xtensa: Enable irqs after cpu is set online 2014-01-14T20:12:41+00:00 Kirill Tkhai tkhai@yandex.ru 2013-12-12T13:41:01+00:00 abf0ea65e0adede5f40a836e6af7f62e7c850546 there is a small possibility that wake_up of softirq thread happens between local_irq_enable() and set_cpu_online(). In this case affinity of the thread changes to fallback affinity (i.e. CPU0). This may be a source of problems. The patch kills that possibility.
