It's a wee bit too cute for my taste as well. I could probably live
with it in the data structures, but having it show up out in places like
Kconfig and filenames goes too far.

For instance, someone seeing memory_aeration.c will have no concept
what's in the file. Could we call it something like memory_paravirt.c?
Or even mm/paravirt.c.

Could you talk for a minute about why the straightforward naming like
"hinted/unhinted" wasn't used? Is there something else we could ever
use this infrastructure for that is not related to paravirtualized free
page hinting?
