Subject: sh: Fixup pte_mkhuge() build failure.
X-Git-Tag: upstream/snapshot3+hdmi~36592^2~20^2~32^2~3

sh: Fixup pte_mkhuge() build failure.

When hugetlbpage support isn't enabled, this can be bogus.
Wrap it back in _PAGE_FLAGS_HARD to avoid changes to the
base PTE when not aiming for larger sizes.
