it's getting late here so i've pushed the current version of those two
patches out to:

git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched.git

I'll redo this git tree if we want some other solution for yield. (but i
think this is the safest approach for 2.6.23 - some apps will complain
about too strong yield, some apps will complain about too weak yield. So
by providing the two extremes we at least cover the practical range of
behavior.)

there's nothing else pending for 2.6.23 otherwise at the moment,
scheduler-wise.
