The current tarball download+unpack+patch+sparse phases will simply be
replaced by an hg clone phase. There are already options to build other
trees as well, i.e. "make linux-2.6-paravirt-build" will build the
latest release of the paravirt_ops tree with Xen support from 
http://xenbits.xensource.com/ext/paravirt_ops/

Each OS tree is expected to carry its own set of self-contained headers
consistent with its needs -- this has always been the case for all trees
apart from the sparse tree. For the tree which is going to be derived
from the sparse tree the build will check that the hypervisor headers
(xen/include/public) and the kernel headers
(linux-FOO.hg/include/xen/interface/) are in sync and error out in order
to prevent those two trees diverging.
