From 910448bbed066ab1082b510eef1ae61bb792d854 Mon Sep 17 00:00:00 2001 From: Janakarajan Natarajan Date: Wed, 14 Jun 2017 11:26:57 -0500 Subject: perf/x86/amd/uncore: Rename cpufeatures macro for cache counters In Family 17h, L3 is the last level cache as opposed to L2 in previous families. Avoid this name confusion and rename X86_FEATURE_PERFCTR_L2 to X86_FEATURE_PERFCTR_LLC to indicate the performance counter on the last level of cache.
