4.4-stable review patch. If anyone has any objections, please let me know.

      2 ../kernel/cpuset.c:2101:11: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
      1 ../kernel/cpuset.c:2101:2: warning: initialization from incompatible pointer type
      1 ../kernel/cpuset.c:2101:2: warning: (near initialization for 'cpuset_cgrp_subsys.fork')

This got introduced by 06ec7a1d7646 ("cpuset: make sure new tasks conform to the current config of the cpuset"). In the upstream kernel, the function prototype was changed as of b53202e63089 ("cgroup: kill cgrp_ss_priv[CGROUP_CANFORK_COUNT] and friends").

That patch is not suitable for stable kernels, and fortunately the warning seems harmless as the prototypes only differ in the second argument that is unused. Adding that argument gets rid of the warning:
