Commit b1f416aa8d870fab71030abc9401cfc77b948e8e breaks vhost_net
because it always registers the virtio_pci_host_notifier_read() handler
function on the ioeventfd, even when vhost_net.ko is using the ioeventfd.
The result is both QEMU and vhost_net.ko polling on the same eventfd
and the virtio_net.ko guest driver seeing inconsistent results:
# ifconfig eth0 192.168.0.1 netmask 255.255.255.0
virtio_net virtio0: output:id 0 is not a head!
To fix this, proceed the same as we do for irqfd: add a parameter to
virtio_queue_set_host_notifier_fd_handler and in that case only set
the notifier, not the handler.

The -numa option to qemu is used to create [fake] numa nodes
and expose them to the guest OS instance.
There are a couple of issues with the -numa option:
a) Max VCPU's that can be specified for a guest while using
the qemu's -numa option is 64. Due to a typecasting issue
when the number of VCPUs is > 32 the VCPUs don't show up
under the specified [fake] numa nodes.
b) KVM currently has support for 160VCPUs per guest. The
qemu's -numa option has only support for upto 64VCPUs
per guest.
This patch addresses these two issues.
Below are examples of (a) and (b)

This patch introduces a new property 'sas_address' which
allows the user to specify the SAS address for the HBA.
The default address is following the NAA locally assigned
identifier format with the locally assigned address
0x525400 as used eg for the MAC addresses.
The lower bytes are set to the pci address which
will ensure uniqueness for the local machine.
The port addresses are now calculated based on the magic
number 0x1221 (which is found in real hardware, too) plus
the device number.

The vlan feature is no longer part of net core. Rename VLANClientState
to NetClientState because net clients are not explicitly associated with
a vlan at all, instead they have a peer net client to which they are
connected.
This patch is a mechanical search-and-replace except for a few
whitespace fixups where changing VLANClientState to NetClientState
misaligned whitespace.

Instead of using VLANState use net/hub.h to support the vlan qdev
property. The vlan qdev property becomes an alias for the peer qdev
property but is represented as a VLAN ID number. When a VLAN ID is
selected the device will really peer with a hub port.

For command line options which permit '?' meaning 'please list the
permitted values', add support for 'help' as a synonym, by abstracting
the check out into a helper function.
This change means that in some cases where we were being lazy in
our string parsing, "?junk" will now be rejected as an invalid option
rather than being (undocumentedly) treated the same way as "?".
Update the documentation to use 'help' rather than '?', since '?'
is a shell metacharacter and thus prone to fail confusingly if there
is a single character filename in the current working directory and
the '?' has not been escaped. It's therefore better to steer users
towards 'help', though '?' is retained for backwards compatibility.
We do not, however, update the output of the system emulator's -help
(or any documentation autogenerated from the qemu-options.hx which
is the source of the -help text) because libvirt parses our -help
output and will break. At a later date when QEMU provides a better
interface so libvirt can avoid having to do this, we can update the
-help text too.

MP initialization protocol differs between cpu families, and for P6 and
onward models it is up to CPU to decide if it will be BSP using this
protocol, so try to model this. However there is no point in implementing
MP initialization protocol in qemu. Thus first CPU is always marked as BSP.
This patch:
- moves decision to designate BSP from board into cpu, making cpu
self-sufficient in this regard. Later it will allow to cleanup hw/pc.c
and remove cpu_reset and wrappers from there.
- stores flag that CPU is BSP in IA32_APIC_BASE to model behavior
described in Inted SDM vol 3a part 1 chapter 8.4.1
- uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP
patch is based on Jan Kiszka's proposal:

Added (msi|msix)_set_message() function for whoever might
want to use them.
Currently msi_notify()/msix_notify() write to these vectors to
signal the guest about an interrupt so the correct values have to
written there by the guest or QEMU.
For example, POWER guest never initializes MSI/MSIX vectors, instead
it uses RTAS hypercalls. So in order to support MSIX for virtio-pci on
POWER we have to initialize MSI/MSIX message from QEMU.

This per-device notifier shall be triggered by any interrupt router
along the path of a device's legacy interrupt signal on routing changes.
For simplicity reasons and as this is a slow path anyway, no further
details on the routing changes are provided. Instead, the callback is
expected to use pci_device_route_intx_to_irq to check the effect of the
change.
Will be used by KVM PCI device assignment and VFIO.

Device assigned on KVM needs to know the mode
(enabled/inverted/disabled) and the IRQ number that a given device
triggers in the attached interrupt controller.
Add a PCI IRQ path discovery function that walks from a given device to
the host bridge, and gets this information. For
this purpose, a host bridge callback function is introduced:
route_intx_to_irq. It is so far only implemented by the PIIX3, other
host bridges can be added later on as required.
Will be used for KVM PCI device assignment and VFIO.
Based on patch by Jan Kiszka, with minor tweaks.

BARs are registered in init functions from memory regions created
by the drivers. Exit functions destroy those memory regions.
By unregistering the io regions after exit(), we're calling
memory_region_del_subregion on freed memory. Don't do that. The
option rom comes along for the ride because it's more symmetric
to how it's created.

Finally, complete the fully specified interface. msix_add_config()
gets folded into msix_init() because we now have quite a few parameters
to pass and rolling it in let's us error earlier, avoiding the ugly
unwind exit path. msix_mmio_setup() also gets rolled in, just because
it's redundant to rediscover offsets when we already have them for
such a tiny function.

MSIX, like PCI, is little endian. Specifying native is wrong here,
but we need to check the rest of the file to determine if it's
as simple as flipping this macro.

msi_init() takes over a BAR without really specifying or allowing
specification of how it does so. Instead, let's split it into
two interfaces, one fully specified, and one trivially easy. This
implements the latter. msix_init_exclusive_bar() takes over
allocating and filling a PCI BAR _exclusively_ for the use of MSIX.
When used, the matching msi_uninit_exclusive_bar() should be used
to tear it down.

bar_size for all users is aligned, let's simply

While virtio-scsi does support multiqueue, the default number of
interrupt vectors is not enough to actually enable usage of
multiple queues in the driver; this is because with only 2
vectors the driver will not be able to use a separate
interrupt for each request queue. Derive the desired number
of vectors from the number of request queues.

Probably due to bad merge months ago, virtio-scsi-pci did not have
ioeventfd support. Fix this and enable it by default, as is the
case for other virtio-pci devices.
