For .31 or new use pv_ops from vanilla git (for dom0 and domU support)

Or vanilla mainstream (actual only domU support) http://kernel.org/

My understanding is that pv_ops will not work with Xen3.3 + 2.6.18 dom0.
The Xen installation I'm using is not - as I understand it - pv_ops
capable. Or am I missing something?

I want to produce loadable modules for recent kernels that will have
pv driver support for Xen3.3. Of course these kernels would run
fine in domU with pvops were they running on a later Xen plus host
kernel, but today's task is to get them running on a standard
Xen3.3 install without pvops support.
Documentation, such as it is, suggests I need to pull down
the kernel source and then compile. I get errors like these:
$ make -C /home/amb/pvdrivers/linux-source-2.6.32 M=$PWD modules
make: Entering directory `/home/amb/pvdrivers/linux-source-2.6.32'

I can copy .o files around, but eventually I get to the point where
it tries to find blkfront.o, and there is no blkfront.c in my kernel
source, nor within unmodified_drivers. Do I need to apply Xen patches to
the source too, and if so where is the best place to get them from?
unmodified_drivers from xenunstable does the same.
