[RFC 0/4 v3] arm64/perf: Add ACPI support

[Jeremy Linton]

This patch set expands upon the patches published by Mark Salter 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 concert with the ACPI/PCIe and ACPI/GICv3
patches. It works well on seattle/juno, but there appears to be a problem with
at least one platform using PPIs (which is questionable as ACPI defines the pmu
interrupt as a GSI). I said a couple weeks ago I would post it, so here it is.

Jeremy Linton (1):
  arm64: pmu: add A72 cpu type, support multiple PMU types

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