Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "Two straggling fixes that I had missed as they were posted a couple of weeks ago, causing problems with interrupts (breaking them completely) on the CSR SiRF platforms" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: arm: prima2: drop nr_irqs in mach as we moved to linear irqdomain irqchip: sirf: move from legacy mode to linear irqdomain
