Subject: [PATCH 0/3] for_each_*_bit: move to find.h and reconsider

for_each_bit() macro family uses find_bit() functions, so it's better
to have for_each_bit() and find_bit() functions in the same header. 

This series puts for_each_bit() to a proper place and optimizes its
usage over the kernel.

The series is based on this:
https://lore.kernel.org/linux-arch/20210612123639.329047-1-yury.norov@gmail.com/

The full series can be found here:

Yury Norov (3):
  include/linux: move for_each_bit() macros from bitops.h to find.h
  find: micro-optimize for_each_{set,clear}_bit()
  Replace for_each_*_bit_from() with for_each_*_bit() where appropriate
