Can you clarify how you're setting the voltages to ensure stability? Tomasz, I didn't mean to suggest this isn't ready for mainline. For the 5420/5800 it seems cpufreq support is a new feature, so this isn't a regression against previous (mainline) behavior. Maybe the big.LITTLE cpufreq support should've been separated out from the cleanup since it's more of a new feature, but that's up to you.
