My implicit suggestion was to add a notice that new patch contributions
to the file from date yyyy-mm-dd on would be declared GPLv2+, as Paolo
has done elsewhere. That would limit the amount of people to ask for a
potential relicensing attempt.

For the record, Anthony explained on IRC that the code originated from
Xen originally and thus qemu-kvm.git does not contain the full history
anyway and that pulling in the Mercurial file history and replaying the
KVM history on top was too difficult, therefore this patch with a single
SoB by Jan.
