[PATCH 0/4] mm: misc cleanups from __GFP_UNMAPPED series

[Brendan Jackman]

In v2 of the __GFP_UNMAPPED series [0], we realised that some of the patches
could potentially be merged as independent cleanups.

These are all independent of one another, if you think some are useful
cleanups and others are pointless churn, it should be fine to just pick
whatever subset you prefer.

No functional change intended.
