Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fix from Thomas Gleixner:
"Fix for a regression caused by the conversion of x86 to the generic
hotplug code.
Instead of doing a plain single line revert, this adds a pile of
comments so the semantics of the force argument are clear"

genirq/cpuhotplug: Revert "Set force affinity flag on hotplug migration"
