This patch is missing:

@@ -476,6 +476,7 @@ static inline void memcpy_from_folio_le16(u16 *to, struct folio *folio,
        do {
                const __le16 *from = kmap_local_folio(folio, offset);
                size_t chunk = len;
+               int i;

                if (folio_test_highmem(folio) &&
                    chunk > PAGE_SIZE - offset_in_page(offset))

I'll send a new version if needed, but I'll wait for other feedback
first.
