which makes the summary line rather misleading, and I really don't think
we need to do this on ARM for the simple reason that we've been doing it
for soo long that it can't be an issue.

I started this as a revert and then realised that it doesn't solve
anything for arm32 without changing the poisoning.

Anyway, if you are happy with how it is, I'll drop the arm32 part. As I
said yesterday, the issue is worse for arm64 with 64K pages.

If you do want to retain the arm32 "mustn't be in the 4K page of
the initrd tail" behaviour then it would probably be a good idea
to document this in the Booting spec.
