Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
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"
* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
irqchip/irq-imx-gpcv2: Fix spinlock initialization
irq/affinity: Fix extra vecs calculation
irq/affinity: Fix CPU spread for unbalanced nodes
