This patch includes changes to xenstore in order to boot as Dom0. This
is different from booting as a guest, since when booted as Dom0
xenstore is not available. This patch sets up a memory page, an
event channel for xenstore and disables xenbus device probing at boot.
It contains a workaround for
Xen PV guests doesn't have a lapic, so disable the lapic call in mca
