Cover letter [PATCH 0/7] Armada 375/38x perf support, and a bonus irqchip driver simplification

This patchset enables support for perf hardware events, by enabling the PMU interrupts in the irqchip driver.
While doing this, we noticed the driver could use some cleaning to simplify the overly complex implementation of the .map(), .unmask() and .mask() functions.
The first three patches are the result of this cleaning effort, while the rest of the series is the Perf support for Armada 375 and Armada 38x SoCs.

The series is based on v3.18-rc1.
Ezequiel Garcia (7):
irqchip: armada-370-xp: Simplify interrupt map, mask and unmask
irqchip: armada-370-xp: Initialize per cpu registers whenCONFIG_SMP=N
irqchip: armada-370-xp: Introduce ais_percpu_irq()helper for
readability
irqchip: armada-370-xp: Enable Performance Counter interrupts

Patches 1 to 4 tentatively applied to irqchip/mvebu. Things have been quiet, so let's get it in next for some more test coverage.
Ezequiel, are these patches really the version we want to see merged? I think you're working on a different implementation that demultiplex the coherency fabric events interrupt.
