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

Pull irq fixes from Thomas Gleixner:
 "Two small fixlets:

   - Add the missing iomu mapping call in the Freescale/NXP/Qualcomm/
     whoever owns it now/ SCFG MSI irqchip driver. Otherwise IRQs wont
     work at all.

   - Fix a SMP=n build warning in the STM32 irq chip driver"
