This patch series adds virtio input devices. It's basically sending
linux evdev events over virtio. There is support for emulated hid
devices (i.e. send usual input to virtio device instead of usb or ps2
device) and for evdev device pass-through.
This depends on mst's virtio-1.0 patches.
Changes in v3:
* sync header with v5 of the kernel driver patch.
[ there was a abi change, testing this series requires v5 of the
kernel patch, the branch below is up-to-date too ]
* minor tweaks.
Changes in v2:
* sync header files from linux & use them.
* added virtio_input_devids struct, pass device ids from host
(requested on guest driver review).
