Well, it doesn't work as intended, I'm afraid:

commit: 51be80edc69390521622df71855d86da4e358488 [67/68] cpufreq: highbank: fix ARM_HIGHBANK_CPUFREQ dependency warning
config: make ARCH=i386 allyesconfig

All warnings:

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