Subject: mm,page_alloc: drop unnecessary checks from pfn_range_valid_contig
pfn_range_valid_contig() bails out when it finds an in-use page or a
hugetlb page, among other things. We can drop the in-use page check since
__alloc_contig_pages can migrate away those pages, and the hugetlb page
check can go too since isolate_migratepages_range is now capable of
dealing with hugetlb pages. Either way, those checks are racy so let the
end function handle it when the time comes.
