Hi,

So what started out as a few reweight fixies, turned into a a few more patches,
but it looks to be solid now.

Thanks for all the testing!

The plan is to stick the first 4 patches (those with a Fixes tag) into
tip/sched/urgent and the rest into tip/sched/core right after -rc1.

These patches have been in queue/sched/core for about a week now, but
I'll wipe that tree to start staging stuff for the post -rc1 tip trees.
