Its needed for the kvm-connector patches later in the series, so it was
included intentionally.

On that topic, I probably should have had a TOC of some kind.  Hmm..let
me hack one together now:

Patch 1: Stand-alone "shared-memory signal" construct, used by various
components in vbus/venet
Patches 2-5: Basic vbus infrastructure
Patches 6-7: IOQ construct, similar to virtio-ring.  Used to overlay
ring-like behavior over the shm interface in vbus
Patches 8-12: virtual-ethernet front and backends
Patch 13: io-apic work to expose the irq-vector in x86, needed for
dynirq support
Patches 14-16: KVM host side support
Patch 17: KVM guest side support

Sorry for the confusion :(

Regards,
-Greg
