[Xen-devel] [PATCH 1/2] xenbus: Fix loopback event channel assuming domain 0

[Daniel De Graaf <dgdegra@xxxxxxxxxxxxx>]

The xenbus event channel established in xenbus_init is intended to be a
loopback channel, but the remote domain was hardcoded to 0; this will
cause the channel to be unusable when xenstore is not being run in
domain 0.
