After changing the parameter from `NotSerialized` to `Serialized`, the
remark is indeed gone and there is no size change.
The remark was added in ACPICA version 20130517 [1] and gives the
following explanation.
If a thread blocks within the method for any reason, and another thread
enters the method, the method will fail because an attempt will be
made to create the same (named) object twice.
In this case, issue a remark that the method should be marked
serialized. ACPICA BZ 909.

IASL stores it's revision in each table header it generates.
That's not nice since guests will see a change each time they move
between hypervisors. We generally fill our own info for tables, but we
(and seabios) forgot to do this for the built-in DSDT.
Modifications in DSDT table:
OEM ID: "BXPC" -> "BOCHS "

Currently, we get SeaBIOS defaults: manufacturer Bochs, product Bochs,
no version. Best SeaBIOS can do, but we can provide better defaults:
manufacturer QEMU, product & version taken from QEMUMachine desc and
name.
Take care to do this only for new machine types, of course.
Note: Michael Tsirkin doesn't trust us to keep values of QEMUMachine member
product stable in the future. Use copies instead, and in a way that
makes it obvious that they're guest ABI.
Note that we can be trusted to keep values of member name, because
that has always been ABI.

It doesn't make sense for a region to be INT64_MAX in size:
memory core uses UINT64_MAX as a special value meaning
"all 64 bit" this is what was meant here.
While this should never affect the spapr system which at the moment always
has < 63 bit size, this makes us hit all kind of corner case bugs with
sub-pages, so users are probably better off if we just use UINT64_MAX

This fixes a crash in hot-unplug of virtio-pci devices behind a PCIe
switch. The crash happens because the ioeventfd is still set whent the
child is destroyed (destruction happens in postorder). Then the proxy
tries to unset to ioeventfd, but the virtqueue structure that holds the
EventNotifier has been trashed in the meanwhile. kvm_set_ioeventfd_pio
does not expect failure and aborts.
The fix is simply to move parts of uninitialization to a new
device_unplugged callback, which is called before the child is destroyed.

Right now we have these pairs:
- virtio_bus_plug_device/virtio_bus_destroy_device. The first
takes a VirtIODevice, the second takes a VirtioBusState
- device_plugged/device_unplug callbacks in the VirtioBusClass
(here it's just the naming that is inconsistent)
- virtio_bus_destroy_device is not called by anyone (and since
it calls qdev_free, it would be called by the proxies---but
then the callback is useless since the proxies can do whatever
they want before calling virtio_bus_destroy_device)
And there is a k->init but no k->exit, hence virtio_device_exit is
overwritten by subclasses (except virtio-9p). This cleans it up by:
- renaming the device_unplug callback to device_unplugged
- renaming virtio_bus_plug_device to virtio_bus_device_plugged,
matching the callback name
- renaming virtio_bus_destroy_device to virtio_bus_device_unplugged,
removing the qdev_free, making it take a VirtIODevice and calling it
from virtio_device_exit
- adding a k->exit callback
virtio_device_exit is still overwritten, the next patches will fix that.

Similar to the PCI bug that prompted these patches, virtio-ccw will
segfault after the reworking of hotplug/hot-unplug. Prepare for
this by moving virtio_ccw_stop_ioeventfd to before the freeing
of the proxy device.
A better place for this could be the device_unplugged callback
for the virtio-ccw bus. However, we do not yet have a callback
that works: this patch avoids the problem while leaving the tree
bisectable.

VERIFY emulation was completely botched (and remained botched through
all the refactorings). The command must be emulated both in check-medium
mode (BYTCHK=00, which we implement by doing nothing) and in check-bytes
mode (which we do not implement yet). Unlike WRITE AND VERIFY (which we
treat simply as WRITE with FUA bit set), VERIFY cannot be handled like
READ. In fact the device is _receiving_ data for VERIFY, not _sending_
it like READ.

- Fix to cleanup MSI-X vectors on shutdown and avoid IRQ route leaks
The KVM-VFIO device support enables KVM to manage how it handles

Airlie had noted that the Nvidia MSI ACK support here may just be
