Subject: [PATCH 2/2] ARM: qcom: Use secondary_startup_arm()
Date: Wed, 21 Jan 2015 11:48:18 -0800 [thread overview]
Message-ID: <1421869698-27341-3-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1421869698-27341-1-git-send-email-sboyd@codeaurora.org>
On qcom platforms we always enter the kernel in ARM mode,
regardless of the kernel being compiled for THUMB mode. Use
secondary_startup_arm() to properly switch the mode to what the
kernel expects if required.
