The patch titled Subject: mm/mremap: start addresses are properly aligned has been removed from the -mm tree. Its filename was mm-mremap-start-addresses-are-properly-aligned.patch This patch was dropped because it had testing failures ------------------------------------------------------ From: Wei Yang <richardw.yang@xxxxxxxxxxxxxxx> Subject: mm/mremap: start addresses are properly aligned After previous cleanup, extent is the minimal step for both source and destination. This means when extent is HPAGE_PMD_SIZE or PMD_SIZE, old_addr and new_addr are properly aligned too. Since these two functions are only invoked in move_page_tables, it is safe to remove the check now.
