Subject: [RESEND PATCH 1/1] bitops.h: move out get_count_order[_long]() from
 __KERNEL__ scope

From: zijun_hu <zijun_hu@....com>

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
("mm-vmalloc-fix-align-value-calculation-error-v2-fix-fix")
