I'm not /that/ sure. The second one affects single stepping only, and
the first one is now redundant as QEMU (and thus also KVM) uses a
compacter way of supporting x86-64 registers. But maybe the patch is
still required for "old" QEMU 0.9.1 (I'm working with development heads
only). But IIRC, the error pattern used to be quite different when QEMU
did not yet support x86-64 registers.
