From 4b36873b4a3455590f686903c354c4716e149c74 Mon Sep 17 00:00:00 2001 From: James Clark Date: Mon, 24 Jul 2023 14:44:57 +0100 Subject: perf/x86: Remove unused PERF_PMU_CAP_HETEROGENEOUS_CPUS capability Since commit bd2756811766 ("perf: Rewrite core context handling") the relationship between perf_event_context and PMUs has changed so that the error scenario that PERF_PMU_CAP_HETEROGENEOUS_CPUS originally silenced no longer exists. Remove the capability to avoid confusion that it actually influences any perf core behavior. This change should be a no-op.
