Pull x86 fix from Thomas Gleixner: "Restore the retrigger callbacks in the IO APIC irq chips. That addresses a long standing regression which got introduced with the rewrite of the x86 irq subsystem two years ago and went unnoticed so far" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/ioapic: Restore IO-APIC irq_chip retrigger callback
