Subject: [PATCH V1 0/6] cgroup,x86/intel_rdt : *pre h/w* Intel code data prioritization support and cgroup changes

This patchset has some preparatory patches to cgroup to add a wrapper to
to cgroup_rmdir to destroy the cgroup directories recursively, new mount
and umount interfaces for ss. It then has patches to support Intel code
data prioritization which is an extension of cache allocation and lets
allocate code and data cache seperately.

Details of the feature can be found in the Intel SDM june 2015 volume 3,
	section 17.16.

The preparatory patches and some part of enabling are tested but
otherwise this is mostly a *pre hardware* patch and I still need to test
it once i setup the hardware.

This patch is dependent on cache allocation patch series V11.

Known issues:
 - Need changes to the formating of the change logs
 - Remove some RDT specific flags in cgroup.c
 - Patch is for initial testing. Will add more documentation on the new
 APIs if needed.
