Subject: [PATCH 3/4] cpu: export cpu hotplug disable/enable functions as global functions
Date: Tue, 7 Aug 2012 16:43:25 +0800 [thread overview]
Message-ID: <1344329006-10645-3-git-send-email-chenhui.zhao@freescale.com> (raw)
In-Reply-To: <1344329006-10645-1-git-send-email-chenhui.zhao@freescale.com>
The cpufreq driver of mpc85xx will disable/enable cpu hotplug temporarily.
Therefore, the related functions should be exported.
