[PATCH] arm64: cpufeature: Export this_cpu_has_cap helper
From: Suzuki K Poulose
Date: Wed Nov 03 2021 - 18:13:08 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
Export the this_cpu_has_cap() for use by modules. This is
used by TRBE driver. Without this patch, TRBE will fail
to build as a module :
ERROR: modpost: "this_cpu_has_cap" [drivers/hwtracing/coresight/coresight-trbe.ko] undefined!
Fixes: 8a1065127d95 ("coresight: trbe: Add infrastructure for Errata handling")
