Can you do this so it clips to any upstream bridge, whether it's a host

ok, please check attached v2.
I wish this were in generic code. There's nothing architecture-specific
about the problem, but this patch only fixes things on x86. Can you make a
similar change in the corresponding code for other arches, as well?
ok, later after x86.
Thanks

I checked (only) v2 of your patch on versions 3.18.0 and 3.18.1. The
result of both versions is that booting stops with kernel panic. I don't
how to get the full log (there is nothing in journalctl and dmesg after
booting some working kernel - maybe if you can give me some hint what to
google) so I will attach photo of screen to the bugzilla issue.
