Heiko Carstens dba6bb6004 s390/mm: optimize copy_page ... Always use the mvcl instruction to copy a page instead of mvpg or a couple of mvc instructions. Copying a huge page is 25% faster this way. Also bypass caches when copying pages since only parts of a page will be used afterwards. Especially when copying a huge page this would kick everything out of the L1 and L2 data caches on a zEC12 machine.
