[PATCH v2 0/3] perf mem amd: Fix few logic bugs

[Ravi Bangoria]

Recent PMU refactoring changes[1] introduced a notion of core vs other
PMUs and made perf mem/c2c code depend only on core PMUs, which is
logically wrong for AMD as perf mem/c2c on AMD depends on IBS OP PMU,
not the core PMU. Although user visible perf mem/c2c functionality is
still working fine, internal code logic is wrong. Fix those.

v1: https://lore.kernel.org/r/20230613095506.547-1-ravi.bangoria@xxxxxxx
v1->v2:
 - Patch #2 of last version is already picked up by Arnaldo. So skip it.
 - Scan all PMUs unconditionally in perf mem code instead of making it
   conditional on arch.

Ravi Bangoria (3):
  perf pmus: Describe semantics of 'core_pmus' and 'other_pmus'
  perf mem amd: Fix perf_pmus__num_mem_pmus()
  perf mem: Scan all PMUs instead of just core ones
