Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Gleixner: - Prevent double activation of interrupt lines, which causes problems on certain interrupt controllers - Handle the fallout of the above because x86 (ab)uses the activation function to reconfigure interrupts under the hood. * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/irq: Make irq activate operations symmetric irqdomain: Avoid activating interrupts more than once
