mainline inclusion
from mainline-5.13-rc1
commit 0a264884
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I3ZGKZ
CVE: NA

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

The vmalloc mapper operates on a struct page * array rather than a linear
physical address, re-name it to make this distinction clear.
