[RFC PATCH 0/3] Series short description

Hi Ingo, Steven, Peter,
This series applies roughly to mainline as an enhancement to the sched_rt
logic. Peter and I were discussing some of the unecessary overhead in
pull_rt_tasks() via IRC, and this is my RFC attempt to address the problem.

I have built/booted this on a 4-way C2D Xeon box and it passes preempt-test.

Comments, please.

-Greg

sched: use highest_prio.next to optimize pull operations
sched: use highest_prio.curr for pull threshold
sched: track the next-highest priority on each runqueue
