I'm getting following build error in the latest staging tree:

Looks like 22167:330c4d9010da and 22170:4e47a7db9711 are individually OK
but the combination is broken. This fixes it:

Sorry about that.  I thought I had build-tested it, but perhaps the
failure was somehow masked by the existing xen-unstable build failure
due to

Thanks, Ian C, for your patch; I have build-tested and applied it.

When I try to execute build for the unstable tree (rev 3280d6211213), I get
the following error messages.
