This series adds topology identification for Intel and AMD processors and uses this identification in the AMD CPPC code to identify the boost numerator. This series was previously submitted as [1], but this was based on some patches in linux-pm/linux-next that will be dropped. Instead the series is now based on tip/master. This also pulls one patch from Pawan's series [2] and adjusts it for all feedback while adding AMD support at the same time.
