arch_prepare_to_swap() derives a page from the folio only for mte_save_tags() to recompute the folio's swap entry from that page. Pass the entry in directly with folio_swap_entry(), matching mte_restore_tags(), and move the page_mte_tagged() check into the caller so we only compute the entry for tagged pages. __mte_invalidate_tags() loses its only user, so remove it and call mte_invalidate_tags() directly in the error path. This removes two calls to compound_head(). No functional change. Signed-off-by: Tal Zussman <redacted> ---
