Arm64 supports gigantic page after
commit 084bd29810a5 ("ARM64: mm: HugeTLB support.")
however, it got broken by
commit 944d9fec8d7a ("hugetlb: add support for gigantic page
allocation at runtime")
This patch selects ARCH_HAS_GIGANTIC_PAGE to make this
function can be used again.
I haven't double checked that the above commit really broke it but if
that is the case then
Fixes: 944d9fec8d7a ("hugetlb: add support for gigantic page allocation at runtime")
would be nice as well I guess. I do not think that marking it for stable
is really necessary considering how long it's been broken and nobody has
noticed...
