Subject: [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 apply
it?

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

From: "Jonghwan Choi <[email protected]>"

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.
