Merge branch 'sched/fast-headers' into sched/core

Merge the scheduler build speedup of the fast-headers tree.

Cumulative scheduler (kernel/sched/) build time speedup on a
Linux distribution's config, which enables all scheduler features,
compared to the vanilla kernel:

    Summary:

      - CPU time used to build the scheduler dropped by -60.9%, a reduction
        from 22.1 clock-seconds to 8.7 clock-seconds.

      - Wall-clock time to build the scheduler dropped by -3.9%, a reduction
        from 2.95 seconds to 2.84 seconds.
