Subject: bitops.h: move out get_count_order[_long]() from __KERNEL__ scope
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=13113475f737723ae55c7b38b4439bb62257c03f;p=deliverable%2Flinux.git

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