[PATCH 0/4] sched fixes and clean-ups

[Juri Lelli <juri.lelli@arm.com>]

Hi all,

while trying to come up with 01/04, I collected the following set of fixes.

Patches 02-04/04 are simple refactoring of code and clean-ups.
Patch 01/04 is instead my attempt to fix a problem highlighted some time
back by Wanpeng Li regarding hotplug and the way SCHED_DEADLINE keeps
track of admission control decisions (admitted bandwidth). This patch
is invasive, but it seems to fix the problem (and I couldn't find
cleaner fixes :-/). Please give special attention to it :-).

Thanks!

Best,

- Juri
