From: zijun_hu <zijun_hu@xxxxxxx>
Subject: bitops.h: move out get_count_order[_long]() from __KERNEL__ scope
move out get_count_order[_long]() definitions from scope limited by macro
__KERNEL__
it not only make both functions available in wider region regardless of
whether __KERNEL__ is defined but also keep original region for
get_count_order() before the recent commit c513b4cd2fe9
