Woops, my bad. I somehow ended up with the full maintainer list for
patch 2/2 from the script but not this one (1/2). Apologies and thanks
for the heads up.
I saw Juergen's patch [0] ("x86/paravirt: remove the wbinvd hook") to
remove the WBINVD hook, so I'll do the same for WBNOINVD in the next
version (meaning I shouldn't need to update xenpv code anymore).

Thanks!
Kevin
