[Fwd: Re: [Xen-devel] [RFC][PATCH] allow dom0 to power off machine using ACPI on shutdown.]
Ewan,
Keir seems to think this patch is OK. I tested it on an
Intellistation A Pro for x86_64 and it works for me. I think it is low
risk because it's executed at the end of the shutdown process. Please
apply.

It might be better to install the hypervisor call in pm_power_off and

That would seem to fit in better with the way the x86 arch handles
multiple power off strategies.
I haven't looked to see how the other architectures do power off yet.
Was hoping for some comment about whether to do power off in xen or in
domU and whether the hypervisor needed notification.
I think your patch looked okay for now, actually. Alternatively our
machine_restart() could be moved into arch-specific code files. Doing
the power off in dom0 is fine -- as you say, Xen doesn't do anyhting
special before shutdown.
