OK, here's something which is more presentable, and it even boots (at
least under Xen; haven't tried native).
paravirt-patch-rename-paravirt_patch.patch
paravirt-use-offset-site-ids.patch
paravirt-fix-clobbers.patch
- misc cleanups
paravirt-patchable-call-wrappers.patch
- wrap a large number of the paravirt calls with the magic to make the
callsites patchable. More are possible; this is just a good first step.
paravirt-patch-machinery.patch
- the actual patching machinery, which is function-pointer driven
rather than table driven now.
