This tag only appears in the cover letter, and is missing in each patch.
It would have been acceptable if it were in the PR tag, but
the tag (which for some reason isn't displayed in your cover letter)
is simply "PV back end support for emulated Xen".

You can fetch a series with tag applied with b4:
