Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Ingo Molnar:
"The changes in this cycle were:
- Remove the irq timings/variance statistics code that tried to
predict when the next interrupt would occur, which didn't work out
as hoped and is replaced by another mechanism.
- This new mechanism is the 'array suffix computation' estimate,
which is superior to the previous one as it can detect not just a
single periodic pattern, but independent periodic patterns along a
log-2 scale of bucketing and exponential moving average. The
comments are longer than the code - and it works better at
predicting various complex interrupt patterns from real-world
devices than the previous estimate.
- avoid IRQ-work self-IPIs on the local CPU
- fix work-list corruption in irq_set_affinity_notifier()"
* 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
irq_work: Do not raise an IPI when queueing work on the local CPU
genirq/devres: Use struct_size() in devm_kzalloc()
genirq/timings: Add array suffix computation code
genirq/timings: Remove variance computation code
genirq: Prevent use-after-free and work list corruption
