Subject: [RESEND PATCH 3.8-stable] cpufreq: exynos: Get booting freq value in
 exynos_cpufreq_init

This patch looks like it should be in the 3.8-stable tree, should we
applyit?

------------------

From: "Jonghwan Choi <jhbird.choi@...sung.com>"

commit 6e45eb12fd1c741d556bf264ee98853b5f3104e5 upstream

Boot_freq is for saving booting freq. But exynos_cpufreq_cpu_init
is called in hotplug. If boot_freq is existed in exynos_cpufreq_cpu_init,
boot_freq could be changed.
