This patch introduces the cgroup/cpuset-v1.c source file which will be used for all legacy (cgroup v1) cpuset cgroup code. It also introduces cgroup/cpuset-internal.h to keep declarations shared between cgroup/cpuset.c and cpuset/cpuset-v1.c. As of now, let's compile it if CONFIG_CPUSET is set. Later on it can be switched to use a separate config option, so that the legacy code won't be compiled if not required.

Don't leave a blank line at the end of a file. You will get the following error when applying the patch.
0001-cgroup_cpuset-introduce-cpuset-v1.c.patch:70: new blank line at EOF. All your patches except the last one have this problem. Cheers, Longman
