[PATCH v6 00/11] Enable PMUs in ACPI systems

Added cpu affinity sysfs entry
Converted pmu_types array, to linked list
Restrict use of the armv8_pmu_probe_table to ACPI systems
Rename MADT parsing routines in smp.c
Convert sysfs PMU name to use index rather than partnum
Remove pr_devel statements
Other Minor cleanups
Add Partial Ack-by Will Deacon

Remove list of CPU types for ACPI systems. We now match a generic
event list, and use the PMCIED[01] to select events which exist on
the given PMU. This avoids the need to update the kernel every time
a new CPU is released.
Update the maintainers list to include the new file.

Correct build issues with ARM (!ARM64) kernels.
Add ThunderX to list of PMU types.

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.

Jeremy Linton (9):
  arm64: pmu: Probe default hw/cache counters
  arm64: pmu: Hoist pmu platform device name
  arm64: Rename the common MADT parse routine
  arm: arm64: Add routine to determine cpuid of other cpus
  arm: arm64: pmu: Assign platform PMU CPU affinity
  arm64: pmu: Provide cpumask attribute for PMU
  arm64: pmu: Add routines for detecting differing PMU types in the
  arm64: pmu: Enable multiple PMUs in an ACPI system
  MAINTAINERS: Tweak ARM PMU maintainers

Mark Salter (2):
  arm64: pmu: add fallback probe table
  arm64: pmu: Add support for probing with ACPI
