Subject: thp-huge-zero-page-basic-preparation-v6
Huge zero page (hzp) is a non-movable huge page (2M on x86-64) filled
with zeros.
For now let's allocate the page on hugepage_init(). We'll switch to lazy
allocation later.
We are not going to map the huge zero page until we can handle it
properly on all code paths.
is_huge_zero_{pfn,pmd}() functions will be used by following patches to
check whether the pfn/pmd is huge zero page.
