Linux v4.0-rc1 vfio-pci introduced a new virtual interrupt to allow
the kernel to request a device from the user. When signaled, QEMU
will by default attmempt to hot-unplug the device. This is a one-
shot attempt with the expectation that the kernel will continue to
poll for the device if it is not returned. Returning the device when
requested is the expected standard model of cooperative usage, but we
also add an option option to disable this feature. Initially this
opt-out is set as an experimental option because we really should
honor kernel requests for the device.

This header has no further dependencies. It only has some stable data
types and primitive functions, so we can copy it to include/hw/virtio in
order to allow vring code (and its user virtio-blk dataplane) to be
built unconditionally, even for cross compiling.

Resync QEMU's copy of the Linux kernel headers from
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit 2ef14f4. This adds the ARM KVM headers, since ARM KVM
support has just hit mainline via Russell's ARM tree.
This is not a pure sync -- I have removed by hand some changes
that would have reverted updates for s390x and ppc which have not
yet hit mainline.
