virtio: remove CONFIG_VIRTIO_RING Everyone who selects VIRTIO is also made to select VIRTIO_RING; just make them synonymous, since we removed the indirection layer some time ago.

virtio: Add platform bus driver for memory mapped virtio device This patch, based on virtio PCI driver, adds support for memory mapped (platform) virtio device. This should allow environments like qemu to use virtio-based block & network devices even on platforms without PCI support. One can define and register a platform device which resources will describe memory mapped control registers and "mailbox" interrupt. Such device can be also instantiated using the Device Tree node with compatible property equal "virtio,mmio".

virtio: PCI device This is a PCI device that implements a transport for virtio. It allows virtio devices to be used by QEMU based VMMs like KVM or Xen.

virtio_pci: add an option to disable legacy driver Useful for testing device virtio 1 compatibility. Based on patch by Rusty - couldn't resist putting that flying car joke in there!

virtio: balloon driver After discussions with Anthony Liguori, it seems that the virtio balloon can be made even simpler. Here's my attempt. The device configuration tells the driver how much memory it should take from the guest (ie. balloon size). The guest feeds the page numbers it has taken via one virtqueue. A second virtqueue feeds the page numbers the driver wants back: if the device has the VIRTIO_BALLOON_F_MUST_TELL_HOST bit, then this queue is compulsory, otherwise it's advisory (and the guest can simply fault the pages back in). This driver can be enhanced later to deflate the balloon via a shrinker, oom callback or we could even go for a complete set of in-guest regulators.
