Yes, I do encounter build issues while using headers from
staging/xen-unstable.  Most of them are in xen_disk.c, xen_backend.c
while calling methods like xc_interface_* or xc_gnttab_* etc.  They
are all trivial to fix locally though there are more than a few places
to fix.  I will make local changes to keep going and Anthony can
confirm and fix the issues when he is back.  I am not attaching the
build errors here as they are readily reproducible when using
staging/xen-unstable headers.
