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:
