Hi Sasha,

I have tried unsuccessfully to reproduce the bug in qemu with 20G RAM,
and 8 CPUs.

Patch "mm: uninitialized struct page poisoning sanity" should be improved
to make dump_page() to detect poisoned struct page, and simply print hex
in such case. I will send an updated patch later.

How do you run this on Microsoft hypervisor? Do I need Windows 10 for
that?

BTW, I am going to be on vacation for the next two week (going to Israel),
so I may not be able to response quickly.

Thank you,
Pasha
