Unify slots_lock acquision around vcpu_run(). This is simpler and less
error-prone.
Also fix some callsites that were not grabbing the lock properly.
Please review.

This patch introduces virtio support over PCI. virtio is a generic virtual IO
framework for Linux first introduced in 2.6.23. Since 2.6.25, virtio has
supported a PCI transport which this patch implements.
Since the last time these patches were posted to qemu-devel, I've reworked it
to use the p
This patch implements the virtio network driver backend. In KVM, this driver
can achieve 1gbit tx/rx performance. More patches are required to improve the
network IO infrastructure to achieve better performance in QEMU.

This patch introduces a PCI DMA API and some generic code to support other DMA
APIs. Two types are introduced: PhysIOVector and IOVector. A DMA API
maps a PhysIOVector, which is composed of target_phys_addr_t, into an IOVector,
which is composed of void *.
This enables zero-copy IO to be preform
uint32_t is the wrong type to use to represent physical addresses.
