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

Pull irq fixes from Thomas Gleixner:
 "The irq department provides:

   - two fixes for the CPU affinity spread infrastructure to prevent
     unbalanced spreading in corner cases which leads to horrible
     performance, because interrupts are rather aggregated than spread

   - add a missing spinlock initializer in the imx-gpcv2 init code"
