Subject: mm: hugetlb: only prep and add allocated folios for non-gigantic pages
Date: Mon, 9 Oct 2023 15:56:05 +0100

Calling prep_and_add_allocated_folios when allocating gigantic pages at
boot time causes the kernel to crash as folio_list is empty and iterating
it causes a NULL pointer dereference.  Call this only for non-gigantic
pages when folio_list has entries.
