Re: [XenPPC] Should the platform name be "Xen-Maple"
Jimi, the context is that we need to modify Fedora's installer so that
it properly detects the system it's running on. That means we're
implementing a user-visible interface right now. I think "Xen-Maple" is
a terrible name to permanently commit ourselves to. Let's not.
PPC's cpuinfo seems to have a split between "platform" and
"machine" (where machine is more specific). I think platform = Xen is
fine, and machine is the underlying machine.
