Subject: [PATCH 0/7] cpumask: repair cpumask_check()

After switching cpumask to use nr_cpu_ids in [1], cpumask_check() started
generating many false-positive warnings. There are some more issues with
the cpumask_check() that brake it.

This series fixes cpumask_check() mess and addresses most of the
false-positive warnings observed on boot of x86_64 and arm64.


Yury Norov (7):
  cpumask: fix checking valid cpu range
  net: fix cpu_max_bits_warn() usage in netif_attrmask_next{,_and}
  cpumask: switch for_each_cpu{,_not} to use for_each_bit()
  lib/find_bit: add find_next{,_and}_bit_wrap
  lib/bitmap: introduce for_each_set_bit_wrap() macro
  lib/find: optimize for_each() macros
  lib/bitmap: add tests for for_each() iterators
