Subject: [PATCH] [RFC] arm64: export this_cpu_has_cap
Date: Fri, 29 Oct 2021 13:30:16 +0200	[thread overview]
Message-ID: <20211029113023.760421-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

It's now used in a coresight driver that can be a loadable module:

ERROR: modpost: "this_cpu_has_cap" [drivers/hwtracing/coresight/coresight-trbe.ko] undefined!

Fixes: 8a1065127d95 ("coresight: trbe: Add infrastructure for Errata handling")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
---
Not sure if we actually want this to be exported, this is my local
workaround for the randconfig build bot.
