It's no secret that I'm fed up with the cavalier attitude to the PVH ABI.

The Xen change that broke Linux PVH guests must be reverted.  This
change may also have broken other guests (e.g., Mirage or one of the
other unikernel OSes).

The documented posted by Roger is a good start, but I'm still not going
to apply any PVH patches to Linux until the ABI is agreed and stable and
the document is committed to the Xen repo.
