mm: merge folio_is_secretmem() and folio_fast_pin_allowed() into gup_fast_folio_allowed()
folio_is_secretmem() is currently only used during GUP-fast. Nowadays,
folio_fast_pin_allowed() performs similar checks during GUP-fast and
contains a lot of careful handling -- READ_ONCE() -- , sanity checks --
lockdep_assert_irqs_disabled() -- and helpful comments on how this
handling is safe and correct.
So let's merge folio_is_secretmem() into folio_fast_pin_allowed(). Rename
folio_fast_pin_allowed() to gup_fast_folio_allowed(), to better match the
new semantics.
