Subject: [PATCH ARM32 v4.4 V2 39/47] ARM: make lookup_processor_type() non-__init
Date: Thu, 1 Aug 2019 13:46:23 +0530 [thread overview]
Message-ID: <8571a7c6a6ff472e0d794311dda2ee4fb64f29eb.1564646727.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1564646727.git.viresh.kumar@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.
