Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 

Pull irq fixes from Thomas Gleixner:
 "A few minor fixlets in ARM SoC irq drivers and a fix for a memory leak
  which I introduced in the last round of cleanups :("

* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  genirq: Fix memory leak when calling irq_free_hwirqs()
  irqchip: spear_shirq: Fix interrupt offset
  irqchip: brcmstb-l2: Level-2 interrupts are edge sensitive
  irqchip: armada-370-xp: Mask all interrupts during initialization.
