Max Filippov	04c6b3e2b5	xtensa: optimize local_flush_tlb_kernel_range Don't flush whole TLB if only a small kernel range is requested. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>	2014-04-06 21:29:17 +04:00
Kirill Tkhai	abf0ea65e0	xtensa: Enable irqs after cpu is set online 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.
