cset 9434 breaks xen/ia64 build

[Alex Williamson]

   FYI, cset 9434 (Switch the default build to make the -xen kernel, not
the -xen0 and -xenU) breaks xen/ia64 as we do not currently have a
linux-defconfig-xen_ia64.  I don't understand why such a change is being
made so close to Xen 3.0.2.  Can we make this architecture dependent?
Thanks,

    Alex

Final release and snapshot to the 3.0-testing tree won't be until the 
end of this week. Please send us a suitable -xen config for ia64.

Can you supply a suitable config? Or is it not possible to have a single
kernel that works as both a dom0 and domU on current ia64?

The change was discussed on xen-devel, and certainly makes sense, at
least on x86. It's not something that would be nice to make arch dep,
but it could be as a hack.

   I'll work on it and either submit a Makefile hack or a suitable -xen
config.  I think xencons vs serial console is the main thing preventing
a combined config file.  Thanks,

Could you elaborate a bit? How is it different from x86?

Thanks,
Ian

   Looks like I was mistaken, CONFIG_VT is the major issue.  I'll send
out a patch shortly that avoids conswitchp in a similar way to x86.
Serial in xen/ia64 is still pretty kludgy, but we'll save that for
another day.  Thanks,

    Alex
