Subject: [PATCH 4.19 11/17] ARM: make lookup_processor_type() non-__init
Date: Wed, 13 Feb 2019 16:32:17 -0500	[thread overview]
Message-ID: <20190213213223.916-12-dave.long@linaro.org> (raw)
In-Reply-To: <20190213213223.916-1-dave.long@linaro.org>

From: Russell King <rmk+kernel@armlinux.org.uk>

Commit 899a42f836678a595f7d2bc36a5a0c2b03d08cbc upstream.

Move lookup_processor_type() out of the __init section so it is callable
from (eg) the secondary startup code during hotplug.
