[PATCH 0/2] arch: enable GENERIC_FIND_FIRST_BIT for MIPS and ARM64

[Yury Norov <yury.norov@xxxxxxxxx>]

MIPS and ARM64 don't implement find_first_{zero}_bit in arch code and
don't enable it in config. It leads to using find_next_bit() which is
less efficient:

It's beneficial to enable GENERIC_FIND_FIRST_BIT as this functionality
is not new at all and well-tested. It provides more optimized code and
saves .text memory:
