[PATCH RFC 0/5] virtio_pci: modern driver

[Michael S. Tsirkin]

Based on Rusty's patches.
Coding style and funny jokes are his.
Bugs and a star wars reference (should be easy to spot) are mine.
Untested, but useful as basis for beginning the qemu work.

TODO:
= 	simplify probing: use a common probe function, probe with modern driver
	first, if that fails - probe with legacy driver.
BUGS:   ATM legacy driver can win and drive a transitional device
        Until this is fixed, to test, disable transitional mode in device

More ideas (optional):
=	allow disabling legacy driver
=	support shared IRQ for config, read ISR
=	allocate VQ ring in chunks, good for large rings
=	use less meory for small VQ ring in chunks, good for large rings

General TODOs:
=	add config generation support
=	move alloc_virtqueue_pages to virtio core, reuse in e.g. ccw
