mainline inclusion
from mainline-master
commit 11364d61314eb97b12d6b6facb1ededada52fcc1
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I5MK7S
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=11364d61314e



----------------------------------------------------------------------

Use bitmap_zalloc()/bitmap_free() instead of hand-writing them.
It is less verbose and it improves the semantic.

While at it, add an explicit include <linux/bitmap.h>.
