Subject: [PATCH 0/3] SCHED_DEADLINE fix AC and SMP scheduling

Hello everyone,

This patchset fixes admission control, bandwidth management and
(clustered) SMP scheduling for SCHED_DEADLINE tasks.

Patch 1/3 properly clears things up when a task leaves SCHED_DEADLINE,
without dying (and it is a different solution for the problem spotted
by Daniel, http://marc.info/?l=linux-kernel&m=140974782707197&w=2);
patch 2/3 fixes how cpusets bandwidth is checked and updated; patch 3/3
fixes SMP (clustered) scheduling.

Best Regards,

- Juri
