If we run with an old kernel that does not support KVM_CAP_IRQ_ROUTING,
we don't have to do anything in the ->register_io_adapter and
->io_adapter_map callbacks and therefore should return 0 instead of
-ENOSYS (just as the non-kvm flic does).
This fixes using adapter interrupts when running under an older kernel,
which broke with "s390x: add I/O adapter registration".

Right now to run firmware inside the QEMU VExpress model requires
padding out the firmware image to the size of the virtual flash and
passing it in via the -pflash argument. If the firmware image is passed
without padding, then QEMU will fail. Also, when passed as a -pflash
argument, QEMU treats the file as persistent storage and will modify the
file.
The -bios flag provides the semantics that we want for providing a
firmware image. This patch maps the contents of the -bios file into the
address space at the boot flash location.
Tested with the vexpress-a15 model and the Tianocore port.

Currently, e1000 support is based on the manual for the 8254xx

CC: Andreas Färber <afaerber@suse.de>
The case statements in the CG3 read and write register routines have a maximum
value of CG3_REG_SIZE, so if a value were written to this offset then it
would overflow the register array.
Currently this cannot be exploited since the MemoryRegion restricts accesses
to the range 0 ... CG3_REG_SIZE - 1, but it seems worth clarifying this for
future review and/or static analysis.

We can pick the usb port speed in generic code, by looking at the port
and device speed masks and looking for the fastest match. So add a
function to do exactly that, and drop the speed setting code from
usb_desc_attach as it isn't needed any more.
This way we can set the device speed before calling port->ops->attach,
which fixes some xhci hotplug issues.

This patch uses the new IOMMU notifiers to allow VFIO pass through devices
to work with guest side IOMMUs, as long as the host-side VFIO iommu has
sufficient capability and granularity to match the guest side. This works
by tracking all map and unmap operations on the guest IOMMU using the
notifiers, and mirroring them into VFIO.
There are a number of FIXMEs, and the scheme involves rather more notifier
structures than I'd like, but it should make for a reasonable proof of
concept.
