please find in attachment an update for the pending patch which disable Xen
on ARM since it is currently broken (compilation fails).
Is it broken upstream or is it broken due to our xen patches?

openSUSE Xen patches brake it, as mentionned here:

Now see - in that mail you point to an upstream patch as the
presumed cause, plus XEN_HAVE_PV_GUEST_ENTRY is _intended_
to be undefined for ARM, which made me ignore it. Would it have
been made clear that it's in our patches (with a more explicit
description as to what the problem really is), I would have gone
and tried to fix this there.

Looking at this in closer detail it's not even clear how to fix this
though, since without a struct start_info instance there's nowhere
to check for SIF_INITDOMAIN. Will need to consult xen-devel first...

And disabling a feature rather than fixing the build is almost always
wrong imo anyway, so the request overall looked bogus to me in
the first place.
