Subject: [PATCH V2 0/4] perf/x86/intel: Constify static structs

Constify a number of static structs which are not modified to allow the
compiler to place them in read-only memory. All in all, it moves ~25kB
to read-only memory (if looking at o-files).

Changes since v1:
- Introduce rkl_uncore_msr_ops to be able to constify skl_uncore_msr_ops
  (now all intel_uncore_ops are const).

Rikard Falkeborn (4):
  perf/x86/intel/uncore: Constify intel_uncore_ops
  perf/x86/intel: Constify static attribute_group structs
  perf/x86/intel/uncore: Constify freerunning_counters
  perf/x86/intel/uncore: Constify unmodified static extra_reg structs
