Hi Konrad,
Finally found the time to test the xen-swiotlb again (together with usb3/xhci isoc pathes)
I began with your tree:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git devel/merge.2.6.35-rc3
and after that i merged in a tree for the xhci part that is based on 2.6.35-rc4:
git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci.git amd-isoc
That all went without a problem, booting the resulting kernel in a PV domU gives the warnings below, i hope these can be addressed before the next merge window and xen-swiotlb will make it in !
Despite the 2 warnings, the usb devices i passed through seem to work ok.

They're merged into xen/next, so you should be able to find them as part
of the history. If you have a local git tree, "git show" should be able
to display the patch unconditionally, and git cherry-pick should bring
each into your branch.

Done.
They are available at
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git devel/merge.2.6.35-rc6
You also need for your Dom0 to have this patch:
xen-pciback: Redo spinlock usage.
You can merge it from
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git pv/pciback-2.6.32
