I don't think this is my issue, without this patch，the warning is still there.

warning: (GENERIC_CPUFREQ_CPU0 && ARM_BIG_LITTLE_CPUFREQ && ARM_EXYNOS5440_CPUFREQ && ARM_HIGHBANK_CPUFREQ) selects PM_OPP which has unmet direct dependencies (ARCH_HAS_OPP)

this warning is caused by commit 109df086e(cpufreq: Select PM_OPP rather than depending on it),
so could you merge this patch? I will send a revert patch to solve this issue, what is your opinion?

Regards,
Kefeng
