Thread-topic: [Xen-ia64-devel] Community effort neededtocatch upwithxen-unstable
Thanks, Kevin and John, for all your hard work to get
this working again.

I haven't looked closely at the patches (Kevin's, and
John's which haven't yet been posted :-)...

Are there any files changed that are NOT ia64-specific?
I want to be very careful about putting files into
xen-ia64-unstable.hg that, if pulled into xen-unstable.hg,
might break Xen/x86.  These should probably be separate
patches so Keir can look at them individually.

Also, once this is all working, we should look at what
it would take to get xenlinux/ia64 built directly from
the xen(-sparse) tree so we won't have to play
"catch up" again.

Logging out for the evening now...
