This patch no longer applies, the delta became much smaller:

Someone needs to bake a proper patch out of this and post it. There must
be also some VGA BIOS differences, but I haven't looked at the details.
That should be resolved at this chance as well.

Basically no more patches, only features that partially require some
refactoring work:

 - KVM in-kernel PIC (patches + dependencies pending)
 - TPR acceleration for Windows (series under review, needs some minor
   further work)
 - MSI rework and support for KVM in-kernel irqchip support
 - PCI device assignment (old-style and/or VFIO)

Then we are done and qemu-kvm can be closed. But I would not expect this
before 1.2, maybe even 1.3. However, once only PCI assignment is
pending, the vast majority of users can switch.
