fbe78f4f55 virtio-net support 
This adds virtio-net support.  This is based on the virtio-net driver 
that exists in kvm-userspace.  This also adds a new qemu_sendv_packet 
which virtio-net requires.

d350d97d19 pci: add default pci subsystem id for all devices (Gerd Hoffman) 
This sets a default PCI subsystem ID for all emulated PCI devices.  PCI
specs require this, so do it.

In many cases it is enougth to know the PCI ID to handle a device
correctly.  Sometimes a device driver must identify the exact piece of
hardware (via PCI Subsystem ID) though.

What does this patch to qemu devices:

Right now the emulated PCI devices have no PCI subsystem ID, only the
PCI ID.  The discussed patch sets a default PCI subsystem ID for all
emulated devices.  Which will make the qemu devices look pretty much
like in the laptop case: all PCI subsystem IDs will point to qemu by
default.

If a driver emulates a very specific piece of hardware where it has to
emulate more than just the PCI chip, it can overwrite the PCI subsystem
ID without problems.  The es1370 driver does that for example.

f65ed4c152 KVM: Coalesced MMIO support 
MMIO exits are more expensive in KVM or Xen than in QEMU because they 
involve, at least, privilege transitions.  However, MMIO write 
operations can be effectively batched if those writes do not have side 
effects.

Good examples of this include VGA pixel operations when in a planar 
mode.  As it turns out, we can get a nice boost in other areas too.  
Laurent mentioned a 9.7% performance boost in iperf with the coalesced 
MMIO changes for the e1000 when he originally posted this work for KVM.

This patch adds support for non-contiguous IO map, which is used by

It also adds the missing legacy IO ports for the PREP PCI bridge and
changes CPU PVR from 74x/75x to 604 to make OS/2 happy.
