Subject: [PATCH 0/6] Cleanup cpumask.h inclusion in core headers

Many core headers include linux/cpumask.h for nothing, and some others
include it just for types. We already have nodemask_types.h, and this
series adds cpumask_types.h to optimize core headers inclusion paths.

Interestingly, it doesn't improve on build time for me, but the headers
cleanup work should keep going.

Yury Norov (6):
  MAINTAINERS: add linux/nodemask_types.h to BITMAP API
  sched: pre-caculate ilog2(TASK_REPORT_MAX)
  cpumask: split out include/linux/cpumask_types.h
  sched: drop dependency on cpumask.h
  cpumask: cleanup core headers inclusion
  cpumask: make core headers including cpumask_types.h where possible
