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

[Jeremy Linton]

v6:
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

v5:
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.

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.


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
    system
  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
