Rusty Russell c9ccf30d77 [PATCH] paravirt: Add startup infrastructure for paravirtualization
1) Each hypervisor writes a probe function to detect whether we are
   running under that hypervisor.  paravirt_probe() registers this
   function.

2) If vmlinux is booted with ring != 0, we call all the probe
   functions (with registers except %esp intact) in link order: the
   winner will not return.
