Merge branch 'timers/nohz-irq-work-v7' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks into timers/nohz
Pull nohz updates from Frederic Weisbecker:
" This set moves the nohz kick, used to notify a full dynticks CPU when
events require tick rescheduling, out of the scheduler tick to a
dedicated IPI.
This debloats a bit the scheduler IPI from off-topic work that was
abusing that scheduler fast path for its convenient asynchronous
properties. Now the nohz kick uses irq-work for its own needs.
Of course this implied quite some background infrastructure rework,
including:
* Clean up some irq-work internals
* Implement remote irq-work
* Implement nohz kick on top of remote irq-work
* Move full dynticks timer enqueue notification to new kick
* Move multi-task notification to new kick
* Remove unecessary barriers on multi-task notification
"
