Kefeng Wang 78fefd04c1 mm: memory: convert clear_huge_page() to folio_zero_user() 
Patch series "mm: improve clear and copy user folio", v2.

Some folio conversions.  An improvement is to move address alignment into
the caller as it is only needed if we don't know which address will be
accessed when clearing/copying user folios.


This patch (of 4):

Replace clear_huge_page() with folio_zero_user(), and take a folio
instead of a page. Directly get number of pages by folio_nr_pages()
to remove pages_per_huge_page argument, furthermore, move the address
alignment from folio_zero_user() to the callers since the alignment
is only needed when we don't know which address will be accessed.
