Subject: [PATCH 0/9] virtio_pci: split out legacy device support

virtio 1.0 support for virtio-pci isn't ready yet.
Therefore, this patchset doesn't make any functional changes.
Instead, this simply refactors virtio-pci, splitting legacy
device support code out to a separate file: virtio_pci_legacy.c

For virtio 1.0, all that's left is to add virtio_pci_modern.c
supporting
	get_features
	finalize_features
	get (config)
	set (config)
	get_status
	set_status
	reset
	setup_vq
	del_vq
	probe
	remove

Most notably, tricky MSI-X vector probing logic stays
in common file: virtio_pci.c. version-specific only has
to code setup/del functions for individual vqs.

Note: this is on top of "virtio 1.0 enhancements"
that I sent earlier.

Michael S. Tsirkin (9):
  virtio_pci: add isr field
  virtio_pci: fix coding style for structs
  virtio_pci: free up vq->priv
  virtio_pci: use priv for vq notification
  virtio_pci: delete vqs indirectly
  virtio_pci: setup vqs indirectly
  virtio_pci: setup config vector indirectly
  virtio_pci: split out legacy device support
  virtio_pci: update file descriptions and copyright
