a6a9239cd8 PCI: Bus number from the bridge, not the device
pcibus_dev_print() was erroneously retrieving the device bus
number from the secondary bus number offset of the device
instead of the bridge above the device.  This ends of landing
in the 2nd byte of the 3rd BAR for devices, which thankfully
is usually zero.

Note: pcibus_get_dev_path() copied this code,
inheriting the same bug.  pcibus_get_dev_path() is used for
ramblock naming, so changing it can effect migration.  However,
I've only seen this byte be non-zero for an assigned device,
which can't migrate anyway, so hopefully we won't run into
any issues.

This patch does not touch pcibus_get_dev_path, as
bus number is guest assigned for nested buses,
so using it for migration is broken anyway.
Fix it properly later.

43849424cf tap: clear vhost_net backend on cleanup
Frontends calling tap_get_vhost_net get an invalid pointer after the
peer backend has been deleted. Jason Wang <jasowang@redhat.com> reports
this leading to a crash in ack_features when we remove the vhost-net
bakend of a virtio nic.

The fix is simply to clear the backend pointer.

543f8e3468 switch stdvga to pci vgabios
Make stdvga provide the new vgabios binary (with pcibios support)
using the PCI option rom bar.  Seabios will happily load it from
there.  The new vga bios will also lookup the framebuffer address
in pci config space, so the magic bochs lfb @ 0xe0000000 is not
needed any more -> zap it.

Without the patch:

  # dmesg | grep framebuffer
  vesafb: framebuffer at 0xe0000000, mapped to 0xf7e80000, using 1875k, total 8192k

3e31375378 spice: add audio
Add support for the spice audio interface.  With this patch applied
audio can be forwarded over the network from/to the spice client.  Both
recording and playback is supported.

The driver is first in the driver list, but the can_be_default flag is
set only in case spice is active.  So if you have the spice protocol
enabled the spice audio driver is the default one, otherwise whatever
comes first after spice in the list.  Overriding the default using
QEMU_AUDIO_DRV works in any case.

d61a4ce8f0 Add Intel HD Audio support to qemu.
This patch adds three devices to qemu:

intel-hda
	Intel HD Audio Controller, the PCI device.  Provides a HDA bus.
	Emulates ICH6 at the moment.  Adding a ICH9 PCIE
	variant shouldn't be hard.

hda-duplex
	HDA Codec.  Attaches to the HDA bus.  Supports 16bit stereo,
	rates 16k -> 96k, playback, recording and volume control
	(with CONFIG_MIXEMU=y).

hda-output
	HDA Codec without recording support.  Subset of the hda-duplex
	codec.  Use this if you don't want your guests access your mic.

Usage: add '-device intel-hda -device hda-duplex' to your command line.

Tested guests:
 * Linux works.
 * Win7 works.
 * DOS (mpxplay) works.
 * WinXP doesn't work.

[ v2 changes ]
 * Fixed endianess, big endian hosts work now.
 * Fixed some emulation bugs.
 * Added immediate command emulation.
 * Added vmstate support.
 * Make it behave like all other sound card drivers:
   - can be configured via '--audio-card-list=hda'
   - can be added to a VM using '-soundhw hda'
 * Code style fixups.
 * Zapped guest-triggerable asserts.
 * Handle partial reads/writes of audio data correctly.
