s390/mm: Convert gmap_make_secure to use a folio

Browse source

[ Upstream commit d35c34bb32 ]

Remove uses of deprecated page APIs, and move the check for large
folios to here to avoid taking the folio lock if the folio is too large.
We could do better here by attempting to split the large folio, but I'll
leave that improvement for someone who can test it.
