It is all well described by Stephen Rothwell who initially spotted that: ----------------------------->8---------------------------- After merging the origin tree, today's linux-next build (arc haps_hs_smp_defconfig+kselftest) produced these warnings:arch/arc/include/asm/perf_event.h:126:27: warning: 'arc_pmu_cache_map' defined but not used [-Wunused-const-variable=] arch/arc/include/asm/perf_event.h:91:27: warning: 'arc_pmu_ev_hw_map' defined but not used [-Wunused-const-variable=] Introduced by commit 0dd450fe13da ("ARC: Add perf support for ARC700 cores") The 2 static arrays should be moved into arch/arc/kernel/perf_event.c (the only place that uses them). We get the warning because perf_event.h is also included by arch/arc/kernel/unaligned.c. ----------------------------->8---------------------------- Could be easily reproduced by running make with "W=1" on any up-to-date sources, when extra warnings get enabled (in particular "-Wunused-const-variable"), otherwise disabled by default in the top-level Makefile as "These warnings generated too much noise in a regular build".
