This patch set supports Intel code data prioritization which is an
extension of cache allocation and allows to allocate code and data cache
seperately. It also includes cgroup interface for the user as seperate
patches. The cgroup interface for cache alloc is also resent.

Details of the feature can be found in the Intel SDM june 2015 volume 3,

*All patches apply on the cache allocation patches v15 and are
dependent on the same*
