sched: get rid of 'new_cpu' in try_to_wake_up()
Clean-up try_to_wake_up(). Get rid of the 'new_cpu' variable in try_to_wake_up() [ that's, one #ifdef section less ]. Also remove a few redundant blank lines. Signed-off-by: Dmitry Adamushko <dmitry.adamushko@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
