The series is the result of this discussion: https://lkml.org/lkml/2017/5/12/665
plus this patch: https://lkml.org/lkml/2017/5/13/137
(I'd like to have it together with others.)

Patch 1 remove useless GENERIC_FIND_FIRST_BIT option.  Patches 2 and 3 change
the order of macros definition and/or headers inclusion for frv and m86k, as
it's needed in patch 4. Patch 4 adds the optimization for find_first_bit() and
find_first_zero_bit(). Patches 5 and 6 consolidate the implementation of
sched_find_first_bit(), and make it local.

According to previous discussion, I added Arnd's ack to patches 5 and 6.
https://lkml.org/lkml/2017/5/15/514 and suggested-by to patch 4.
Arnd, are you OK with it?

Yury Norov (6):
  arch: remove GENERIC_FIND_FIRST_BIT
  m68k: make __ffs and ffz defined prior to including find.h
  frv: make __ffs() visible for find.h
  find_first{,_zero}_bit: unroll search cycle for small bitmaps
  alpha: drop custom implementation for sched_find_first_bit()
  sched: move sched_find_first_bit() from bitops.h to
    kernel/sched/sched.h
