Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Gleixner:
"This contains:
- a series of fixes for interrupt drivers to prevent a potential race
when installing a chained interrupt handler
- a fix for cpumask pointer misuse
- a fix for using the wrong interrupt number from struct irq_data
- removal of unused code and outdated comments
- a few new helper functions which allow us to cleanup the interrupt
handling code further in 4.3
I decided against doing the cleanup at the end of this merge window
and rather do the preparatory steps for 4.3, so we can run the final
ABI change at the end of the 4.3 merge window with less risk"
