Subject: [PATCH 00/24] Complete EEVDF

Hi all,

So after much delay this is hopefully the final version of the EEVDF patches.
They've been sitting in my git tree for ever it seems, and people have been
testing it and sending fixes.

I've spend the last two days testing and fixing cfs-bandwidth, and as far
as I know that was the very last issue holding it back.

These patches apply on top of queue.git sched/dl-server, which I plan on merging
in tip/sched/core once -rc1 drops.

I'm hoping to then merge all this (+- the DVFS clock patch) right before -rc2.

Aside from a ton of bug fixes -- thanks all! -- new in this version is:

 - split up the huge delay-dequeue patch
 - tested/fixed cfs-bandwidth
 - PLACE_REL_DEADLINE -- preserve the relative deadline when migrating
 - SCHED_BATCH is equivalent to RESPECT_SLICE
 - propagate min_slice up cgroups
 - CLOCK_THREAD_DVFS_ID
