This series implements separation of dom0 into separate hardware and
control domains. It uses the capabilities idea from Hyperlaunch -
hardware, control, and xenstore. It's been tested with dom1 as
control, dom2 as a domU, and dom3 as hardware and xenstore.
To keep things more managable, this v2 is only the ARM hypervisor changes,
and one associated init-dom0less change. The series is slightly
re-ordered to move xenstore changes ahead of adding the capabilities.
Setting hardware domain as domid 0 is removed.
I've been unable to run a combined control/xenstore. Linux console
output stops shortly after the domain determines it should be XS_LOCAL.
I have not investigated further.
