pm: introduce new interfaces schedule_work_on() and queue_work_on()
This interface allows adding a job on a specific cpu. Although a work struct on a cpu will be scheduled to other cpu if the cpu dies, there is a recursion if a work task tries to offline the cpu it's running on. we need to schedule the task to a specific cpu in this case. http://bugzilla.kernel.org/show_bug.cgi?id=10897 [oleg@tv-sign.ru: cleanups] Signed-off-by: Zhang Rui <rui.zhang@intel.com> Tested-by: Rus <harbour@sfinx.od.ua> Signed-off-by: Rafael J.
