This is to fix an issue of sleeping in atomic context when processing
hotplug notifications in Exynos MCT(Multi-Core Timer).
The issue was reproducible on Exynos 3250 (Rinato board) and Exynos 5420
(Arndale Octa board).
Whilst testing cpu hotplug events on kernel configured with DEBUG_PREEMPT
and DEBUG_ATOMIC_SLEEP we get following BUG message, caused by calling
request_irq() and free_irq() in the context of hotplug notification
(which is in this case atomic context).
Applied as a 4.2 fix.
Should it be tagged stable@ ?
I have that one queued in tip/timers/urgent already. Please check my
branches before picking up stuff.
Mmmh, yep. I thought I refreshed my branch. Now I see it.
Thanks for the heads up.
