prepare_hugepage_range() performs almost the same checks for all architectures that define it, with the exception of mips and loongarch that also check for overflows. The rest checks for the addr and len to be properly aligned, so we can move that to hugetlb_get_unmapped_area() and get rid of a fair amount of duplicated code.
