[GIT PULL] cgroup changes for v3.7-rc1

[Tejun Heo <tj@kernel.org>]

Hello, Linus.

This is cgroup updates for v3.7-rc1.

* xattr support is added.  The implementation is shared with tmpfs.
  The usage is restricted and intended to be used to manage per-cgroup
  metadata by system software.  tmpfs changes are routed through this
  branch with Hugh's permission.

* cgroup subsystem ID handling simplified.

Please pull from the following branch to receive the above changes.

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git for-3.7

Thanks.
