  - userfaultfd: fix a crash in UFFDIO_MOVE when PMD is a migration entry When UFFDIO_MOVE encounters a     migration PMD entry, it proceeds with obtaining a folio and accessing it even though the entry is     swp_entry_t. Add the missing check and let split_huge_pmd() handle migration entries. While at it also     remove unnecessary folio check.
