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
