The first is for 2.6.21; it is an urgent bugfix, please apply. The second backs out the first; it is required to avoid conflicts with later work which has been done on the paravirt-ops code. It should be added to subsystem queues which are being held for 2.6.22. The third illustrates the form the fix will likely take after the paravirt-ops queue is applied, but is for demonstration purposes only. Zach
