3.12 merge window exynos cpufreq driver fails to build

[Josh Boyer]

Using Linus' tree as of this morning (v3.11-2654-g458c3f6), the
exynos-cpufreq driver doesn't build because it includes a file that
doesn't exist.

+ make -s ARCH=arm V=1 -j4 bzImage KALLSYMS_EXTRA_PASS=1
arch/arm/kernel/return_address.c:63:2: warning: #warning "TODO:
return_address should use unwind tables" [-Wcpp]

make[2]: *** [drivers/cpufreq/exynos-cpufreq.o] Error 1

I'm guessing that <plat/cpu.h> file is supposed to come from
arch/arm/plat-samsung/include/plat/, but I don't see anything that
specifies a -I there.

Thoughts?
