These patches have all been posted before and not picked up yet.  I've
built the folio patches on top of them; while they are not necessarily
prerequisites in the conceptual sense, I'm not convinced that the
folio patches will build without them.  The nth_page patch is purely
an efficiency question, while patch 5 ("Make compound_head
const-preserving") is required for the current implementation of
page_folio().  Patch 8 ("Fix struct page layout on 32-bit systems")
is required for the struct folio layout to match struct page layout
on said 32-bit systems (arm, mips, ppc).

They are on top of next-20210430

I'm running them since a couple days on an arm64 machine which uses the
page_pool API. No issues so far.

Thanks!  Andrew picked up the first seven of these patches last night,
and I resent the eighth one today:
