Hi all,
It looks like all the arm test for linus [1] and next [2] tree
are now failing. x86 seems to be mostly ok.
The bisector fingered the following commit:
commit 0ee930e6cafa048c1925893d0ca89918b2814f2c
Author: Matthew Wilcox <willy@xxxxxxxxxxxxx>
Date: Tue Mar 5 15:46:06 2019 -0800
mm/memory.c: prevent mapping typed pages to userspace
Pages which use page_type must never be mapped to userspace as it would
destroy their page type. Add an explicit check for this instead of
assuming that kernel drivers always get this right.

I have tried the latest linus mater as Dom0 and see some issue to get the
console guest:
42sh> sudo xl create -c ~/works/guest/guest.cfg
Parsing config from /home/julien/works/guest/guest.cfg
xenconsole: Could not read tty from store: Success
I have added a print in the error path added by the commit above to see
what and where it happens:
