Subject: [PATCH 0/4] cpumask: add missing API and simplify cpumask_any_housekeeping()

From: Yury Norov [NVIDIA] <yury.norov@...il.com>

cpumask library missed some flavors of cpumask_any_but(), which makes
users to workaround it by using less efficient cpumask_nth() functions.

Yury Norov (4):
  relax cpumask_any_but()
  find: add find_first_andnot_bit()
  cpumask_first_andnot
  resctrl
