Subject: [PATCH 0/2] sched: Avoid frequent cross taskgroup switches -v2

As I did not hear any other comments on v1, I am assuming that the
above mentioned case of giving buddy privilege to a SCHED_IDLE task
from one cgroup when there is a non SCHED_IDLE task in other cgroup
is not an important case to handle and keeping this change simpler is better.

So, I am going with Paul's suggestion of sticking with original change,
with some cleanups to handle the frequent CR3 switches problem.

Here is the v2 version of the change, split into two patches.
