[PATCH 0/4] 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.
