Very high CPU values in top on idle system (3.0-rc1)

[Markus Trippelsdorf]

I get very high CPU values when I run 'top' on my (mostly) idle system
with 3.0-rc1. For example mpd was always in the 1-2% range and is now
constantly over 50%. 

This is caused by:

commit 317f394160e9beb97d19a84c39b7e5eb3d7815a8

    sched: Move the second half of ttwu() to the remote cpu

When I revert the above I see sane CPU values again.
