I don't understand the question. The above tree is a pv_ops kernel, with 
additional patches applied so it can be a full Xen dom0 (including netback, 
etc).  I'm only sporadically updating it as I need to, so you probably just 
want the oprofile patch [1] if you want to apply it to some other kernel.
