It does seem better to have all of them explicity annotated anyway, even
if it not required in most of the cases because they include
<linux/sched.h> and the annotation in the declaration takes effect.

Note that in order for this to be fully effective, all functions called
from sched_clock() need to be notrace too.  OMAP and u300 miss this.
The following patches fix them up; perhaps you can fold them into this
one.  If not, I will rebase them later after this series is merged:
