Thanks, we need "#ifdef CONFIG_HUGETLB_PAGE" for the added code.
And this patch is still under discussion and needs to be updated.
So Andrew, could you drop the following patches from linux-mm?

mmhwpoison-make-get_hwpoison_page-call-get_any_page.patch added to -mm tree
mmhwpoison-fix-race-with-compound-page-allocation.patch added to -mm tree
