Subject: linux-next: build warnings in Linus' tree

Hi all,

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.
