This series updates mlock to use folios, converting the internal interface
to using folios exclusively and exposing the folio interface externally.

As a product of this moves to using a folio batch rather than a pagevec for
mlock folios, which brings it in line with the core folio batches contained
in mm/swap.c.

This performs the same task as pagevec_reinit(), only modifying a folio
batch rather than a pagevec.

This brings mlock in line with the folio batches declared in mm/swap.c and
makes the code more consistent across the two.

The existing mechanism for identifying which operation each folio in the
batch is undergoing is maintained, i.e. using the lower 2 bits of the
struct folio address (previously struct page address). This should continue
to function correctly as folios remain at least system word-aligned.

All invoctions of mlock() pass either a non-compound page or the head of a
THP-compound page and no tail pages need updating so this functionality
works with struct folios being used internally rather than struct pages.

In this patch the external interface is kept identical to before in order
to maintain separation between patches in the series, using a rather
awkward conversion from struct page to struct folio in relevant functions.

However, this maintenance of the existing interface is intended to be
temporary - the next patch in the series will update the interfaces to
accept folios directly.

This patch updates the mlock interface to accept folios rather than pages,
bringing the interface in line with the internal implementation.

munlock_vma_page() still requires a page_folio() conversion, however this
is consistent with the existent mlock_vma_page() implementation and a
product of rmap still dealing in pages rather than folios.

OK so this is a product of motorola_pgtable.h defining pmd_page() as NULL and
the type magic in page_folio() getting confused. Easy fix, will spin a v2.

We now pass folios to these functions, so update the documentation
accordingly.

Additionally, correct the outdated reference to __pagevec_lru_add_fn(), the
referenced action occurs in __munlock_folio() directly now.
