The most are some folio conversions, another improvement is that move
address alignment into the caller as it is only needed if we don't know
which address will be accessed when clear/copy user folio.

v2:
- rename clear_large_folio to folio_zero_user and move alignment out,
  per Matthew, but still use addr_hint name since it is for cache hint,
  or maybe user_addr_hint ?
- improve copy_user_large_folio() and rename pages_per_huge_page
- add ACK
