[RESEND PATCH v4 0/4] sched: Miscellaneous isolation related cleanups

[Waiman Long <longman@redhat.com>]

 v4:
  - Make "isolcpus=nohz" equivalent to "nohz_full" as suggested by
    Federic.
  - Update the scheduler code to use HK_TYPE_KERNEL_NOISE.

 v3:
  - Fix incorrect housekeeping_nohz_full_setup() flags setting.

 v2:
  - Remove HK_TYPE_SCHED and related dead code
  - Change consolidated name from HK_TYPE_NOHZ_FULL to
    HK_TYPE_KERNEL_NOSISE as suggested by Frederic and update
    isolation.c as well.

This series contains a number of miscellaneous sched/isolation related
cleanups. Other than reducing the number of cpumasks in the housekeeping
structure, there should be no other functional change.
