cpu_down() code is ok wrt sched_idle_next() placing the 'idle' task not at the beginning of the queue. So get rid of activate_idle_task() and make use of activate_task() instead. It is the same as activate_task(), except for the update_rq_clock(rq) call that is redundant. Code size goes down: text data bss dec hex filename 47853 3934 336 52123 cb9b sched.o.before 47828 3934 336 52098 cb82 sched.o.after Signed-off-by: NDmitry Adamushko <dmitry.adamushko@gmail.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
