Applied 1-3 to cgroup/for-7.3.

While applying, fixed a comment typo in patch 1:

-                       else if (cs->dl_bw_cpu >= 0) /* && cacnel */
+                       else if (cs->dl_bw_cpu >= 0) /* && cancel */

The following selftest issues remain. Let's address them with follow-up
patches:

- cpu_set_equal() iterates sizeof(mask) bytes rather than bits, so only
   CPUs 0-7 are compared, and the assert compares a byte count against
   CPU_SETSIZE bits so it always holds.

- thread_b doesn't wait for thread_a before advancing test_phase to
   AFFINITY_THREADS_READY, so the main thread can read affinity_a_before
   before thread_a has written it.

- On a machine which doesn't have both CPUs 0 and 1 online, the test
   fails instead of skipping.

Will fix the selftest in a follow-up patch.

Cheers,
Longman
