[PATCH] virtio_pci updates
This patch brings the virtio_pci driver up-to-date with what I have locally.
It fixes a bug with destroying a virtqueue, switches to kmalloc so we can
support rings > PAGE_SIZE, and fixes a bug with odd sized configuration
entries.

[PATCH v2 06/10] virtio_pci: setup vqs indirectly
VQ setup is mostly version-specific, add another level of indirection to
split the version-independent code out.

[PATCHv5 3/3] virtio_pci: optional MSI-X support
This implements optional MSI-X support in virtio_pci.
MSI-X is used whenever the host supports at least 2 MSI-X
vectors: 1 for configuration changes and 1 for virtqueues.
Per-virtqueue vectors are allocated if enough vectors
available.

[PATCH 1/9] virtio_pci: remove struct virtio_pci_vq_info
We don't really need struct virtio_pci_vq_info, as most field in there
are redundant:
- the vq backpointer is not strictly neede to start with
- the entry in the vqs list is not needed - the generic virtqueue already
has list, we only need to check if it has a callback to get the same
semantics
- we can use a simple array to look up the MSI-X vec if needed.
- That simple array now

[PATCHv3 2/2] virtio: refactor find_vqs
This refactors find_vqs, making it more readable and robust, and fixing
two regressions from 2.6.30:
- double free_irq causing BUG_ON on device removal
- probe failure when vq can't be assigned to msi-x vector
(reported on old host kernels)
An older version of this patch was tested by Amit Shah.
