[PATCH 00/10] 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.

Matthew Wilcox (Oracle) (10):
mm: Remove PageActive
mm: Remove PageSwapBacked
mm: Remove PageReadahead
mm: Remove PageSwapCache
mm: Remove PageUnevictable
mm: Remove PageMlocked
mm: Remove PageOwnerPriv1
mm: Remove page_has_private()
mm: Rename PG_mappedtodisk to PG_owner_2
x86: Remove PG_uncached
