Subject: [PATCH] arm64: cpufeature: Export this_cpu_has_cap helper
Date: Wed,  3 Nov 2021 22:12:56 +0000	[thread overview]
Message-ID: <20211103221256.725080-1-suzuki.poulose@arm.com> (raw)

From: Arnd Bergmann <arnd@arndb.de>

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")
