Hi, It seems that in mainline kernel big.LITTLE switcher support may be usable only on ARM Versatile Express TC2 platform (but even this platform doesn't enable it in its defconfig). The following patchset removes big.LITTLE switcher support (from both ARM core and arm_big_little CPUfreq driver) in favor of using HMP. Since HMP support at scheduler level is not yet merged this patchset is probably premature and thus is marked as RFC.
