[PATCH 0/8] Folio Prequel patches

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

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
