X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d490b3e2c23369c6adfa183d18d9a24ced247797;p=openwrt%2Fstaging%2Fblogic.git Merge branch 'timers/nohz-irq-work-v7' of git://git./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 " Signed-off-by: Ingo Molnar --- d490b3e2c23369c6adfa183d18d9a24ced247797
