[PATCH 0/4] Fix various bits of AC and PI for SCHED_DEADLINE

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

Hi all,

this is basically a resend of 4 patches fixing problems around AC
and PI related to SCHED_DEADLINE. You can find the full story here:

 - https://lkml.org/lkml/2014/9/19/134
 - https://lkml.org/lkml/2014/9/24/493

First two patches fix AC. They are the same as the previous version,
plus aligning to commit f10e00f4bf36 ("sched/dl: Use dl_bw_of() under
rcu_read_lock_sched()"). Last two fix PI.

Thanks a lot again to Daniel for spending time fixing and testing
the PI stuff! And to Peter and Vincent for reviews and comments.

Best Regards,

- Juri
