Enable ARM performance monitoring units on ACPI/arm64 machines.
This patch expands and reworks the patches published by Mark Salter in order to clean up a few of the previous review comments, as well as add support for A72's and big/little configurations.
I've been testing this patch in convert with an assortment of ACPI patches to enable things like PCIe. Its been tested on juno, seattle and some xgene systems.
Thanks,

Mark Salter (3): arm: pmu: Fix non-devicetree probing arm64: pmu: add fallback probe table arm64: pmu: Add support for probing with ACPI
