Sorry!

Sorry, I haven't pushed this upstream yet, since there didn't seem to
be any particular urgency.  What's the dependency?

   J

Here's the description again:

    Frontends are expected to write their protocol ABI to xenstore.  Since
    the protocol ABI defaults to the backend's native ABI, things work
    fine without that as long as the frontend's native ABI is identical to
    the backend's native ABI.  This is not the case for xen-blkfront
    running 32-on-64, because its ABI differs between 32 and 64 bit, and
    thus needs this fix.

I can break the dependency by putting the same bug that is now in
xen-blkfront into xen-fbfront and xen-kbdfront.
