Hi John,

Good catch, and thanks for the detailed explanation. It looks like
riscv and powerpc have equivalent problems in their huge_pte_alloc
implementations, perhaps it's worth taking a look at those. (riscv
looks like it has precisely the same problem except it's a WARN, but
powerpc looks more interesting.)

Either way,

Acked-by: James Houghton <jthoughton@xxxxxxxxxx>

Thanks for the ack, and yes, riscv and powerpc do look like the
same problem to me, too. I'm glad you thought to look there, as
I have fallen into tunnel vision while investigating this, heh.

OK, as long as I'm here, let me fix those up, too. I'll make those
a separate patch, because they are still in the "fragile" state,
rather than actually at the full crash state. :)


thanks,
