[Xen-devel] [PATCH v2] x86/xen: add tty0 and hvc0 as preferred consoles for dom0

[Juergen Gross <jgross@xxxxxxxx>]

Today the tty0 and hvc0 consoles are added as a preferred consoles for
pv domUs only. As this requires a boot parameter for getting dom0
messages per default, add them for dom0, too.
