Subject: [PATCH v3 0/2] cgroup: add pids subsystem

This is a further updated version of the nproc v2 patchset[1] from
advice given by Tejun Heo[2]. The main changes include:

* Switching from mm/page_counter (which is a memcg implementation
  feature) to a pid-controller-specific hierarchical charge/uncharge
  counter with limits implementation using atomic_long_t (which is also
  lockless as it is based on page_counter).

* Updates to the user-space interface to allow for the setting of no
  limit to the number of pids in a cgroup (-1 == unlimited) as well as
  renaming of the files and the removal of nproc.max_limit.

* The controller was renamed to `pids`.
