[PATCH v5.4.y 0/4] sched/deadline: Fix panic due to nested priority inheritance

[Ankit Jain]

When a CFS task that was boosted by a SCHED_DEADLINE
task boosts another CFS task (nested priority inheritance),
Kernel panic is observed.
Fixing priority inheritance changes the way how sched_deadline
attributes are being inherited from original donor task.

Additional supporting patches are added to fix throttling of
boosted tasks.
