Subject: [PATCH] mm: Remove a sentence from kmap_local_folio() kdocs
In the kdocs of kmap_local_folio() there is a an ambiguous sentence
which suggests to use this API "only when really necessary".
On the contrary, since kmap() and kmap_atomic() are deprecated, both
kmap_local_folio(), as well as kmap_local_page(), must be preferred
to the previous ones.
Therefore, remove the above-mentioned sentence.
