From: Janakarajan Natarajan Date: Wed, 14 Jun 2017 16:26:57 +0000 (-0500) Subject: perf/x86/amd/uncore: Rename cpufeatures macro for cache counters X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=910448bbed066ab1082b510eef1ae61bb792d854;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git 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.
