Merge remote-tracking branch 'remotes/mst/tags/for_upstream' into staging
virtio, vhost: fixes for 2.5
This fixes a performance regression with virtio 1,
and makes device stop/start more robust for vhost-user.
virtio devices on pcie bus now have pcie and pm
capability, as required by the PCI Express spec.
migration now works better with virtio 9p.

* remotes/mst/tags/for_upstream:
virtio-9p: add savem handlers
hw/virtio: Add PCIe capability to virtio devices
vhost: send SET_VRING_ENABLE at start/stop
vhost: rename RESET_DEVICE backto RESET_OWNER
vhost-user: modify SET_LOG_BASE to pass mmap size and offset
virtio-pci: unbreak queue_enable read
virtio-pci: introduce pio notification capability for modern device
virtio-pci: use zero length mmio eventfd for 1.0 notification cap when possible
KVM: add support for any length io eventfd
memory: don't try to adjust endianness for zero length eventfd
virtio-pci: fix 1.0 virtqueue migration
