Subject: [PATCH v2 1/9] ARM: correct secondary_startup_arm mode
Date: Sat, 16 May 2015 15:58:22 +0800 [thread overview]
Message-ID: <1431763110-443-2-git-send-email-yingjoe.chen@mediatek.com> (raw)
In-Reply-To: <1431763110-443-1-git-send-email-yingjoe.chen-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>
secondary_startup_arm is used as ARM mode secondary start up function
when ther kernel is compiled in THUMB mode, however the label itself
is still in .thumb mode. readelf shows:
160979: c020a581 120 FUNC GLOBAL DEFAULT 2 secondary_startup_arm
Make sure the label is in ARM mode as well.
