While I'm on the subject, there's a very large diff between the
xen-unstable internal xenlinux tree (linux-2.6.16.13-xen) and the
standalone xenlinux tree (linux-2.6-xen.hg). For example, oprofile
won't compile in the external xenlinux tree. Could we sync them up,
either by applying this patch wholesale or cherry-picking the
important bits bits from it? alternatively, just basing both trees on
the exact same kernel version will reduce the diff significantly.
Cheers,
Muli
