From f04b611e66503336bbdac04eb5a76d62932ce2e3 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Wed, 4 Sep 2024 19:41:54 +0100 Subject: perf/arm-cmn: Clean up unnecessary NUMA_NO_NODE check Checking for NUMA_NO_NODE is a misleading and, on reflection, entirely unnecessary micro-optimisation. If it ever did happen that an incoming CPU has no NUMA affinity while the current CPU does, a questionably- useful PMU migration isn't the biggest thing wrong with that picture...
