[PATCH 0/6 v4] arm64/perf: Add ACPI support

[Jeremy Linton]

v3->v4:
Correct build issues with ARM (!ARM64) kernels.
Add ThunderX to list of PMU types.

v3:
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 newer CPUs and big/little configurations.

I've been testing this patch in concert with an assortment of ACPI
patches to enable things like PCIe. Its been tested on juno, seattle
and some xgene systems.

Thanks,
