I have applied the following patch for today:

From: Stephen Rothwell <redacted>
Date: Tue, 2 Feb 2021 19:49:00 +1100
Subject: [PATCH] make is_pinnable_page a macro

As it is currently defined before page_to_section() which it needs.

Signed-off-by: Stephen Rothwell <redacted>

I still see the same problem in next-20210203, and your patch below
fixes it for me.
Did you drop it from the latest build?

After the most recent build errors, I tried to apply Pavel's patch
  https://lore.kernel.org/linux-mm/CA+CK2bBjC8=cRsL5VhWkcevPsqSXWhsANVjsFNMERLT8vWtiQw@mail.gmail.com/ (local)
but patch said that it was already applied (by Andrew I think),
so I bailed out (gave up).

As far as I can tell, there are two different bugs that got mixed up, and
we need both Pavel's patch (which is now in -next) and Stephen's
(which got dropped again).
