mm: remove PageActive
Patch series "Simplify the page flags a little".
In the course of our folio conversions, we have made many page flags only
used on folios, so we can now remove the page-based accessors. This
should cut down compile time a little, and prevent new users from cropping
up.
There is more that could be done in this area, but it would produce merge
conflicts, so I'll sit on those patches until next merge window. We now
have line of sight to removing PG_private_2 and PG_private.
This patch (of 10):
This flag is now only used on folios, so we can remove all the page
accessors.
