Subject: [PATCH v4 0/3] arch_topology, ACPI: populate cpu capacity from CPPC

Hi all,

v3->v4:
 - v3 can be found at [3]
 - rebased on linux-next 20220310 which contains patches at [4]
   requested by Rafael
 - 2/3 fixed obsolete comment as reported by Yicong at [5]
 - Kept Acked-by,Tested-by as v4 has no code changes compared
   to v3, but only a comment fix.

v2->v3:
 - v2 can be found at [2]
 - Added sanity checking on perf_caps.highest_perf

v1->v2:
 - v1 can be found at [1]
 - Changed debug prints to the format used on the DT path
 - s/init_cpu_capacity_cppc/topology_init_cpu_capacity_cppc

Patches are based on linux next 20220310.

  x86, ACPI: rename init_freq_invariance_cppc to
    arch_init_invariance_cppc
  arch_topology: obtain cpu capacity using information from CPPC
  arm64, topology: enable use of init_cpu_capacity_cppc()
