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, section 17.16. *All patches apply on the cache allocation patches v15 and are dependent on the same* https://lkml.org/lkml/2015/10/2/72 Changes in v2: - Fix some compilation warnings - Port to 4.3-rc.
