Michael S. Tsirkin 817e0b6fe8 pci: interrupt pin documentation update
Fix up some erroneous comments in code:
interrupt pins are named A-D, the
interrupt pin register is always readonly
and isn't zeroed out on reset.

Isaku Yamahata b80d4a9887 pci: don't overwrite multi functio bit in pci header type.
Don't overwrite pci header type.
Otherwise, multi function bit which pci_init_header_type() sets
appropriately is lost.
Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero
which is already zero cleared.

how to test:
run qemu and issue info pci to see whether a device in question is
normal device, not pci-to-pci bridge.
This is handy because guest os isn't required.

Gerd Hoffmann 81a322d4a1 qdev: add return value to init() callbacks.
Sorry folks, but it has to be.  One more of these invasive qdev patches.

We have a serious design bug in the qdev interface:  device init
callbacks can't signal failure because the init() callback has no
return value.  This patch fixes it.

We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu
segfault.  This patch fixes it.

With usb+scsi being converted to qdev we'll get more devices where the
init callback can fail for various reasons.

Juan Quintela 10ee2aaa41 Remove unneded ac97 indirection accessing its state
Searching for "inspiration" to convert another device to qdev, I got
ac97.  Once I understood a bit of qdev, found that ac97 used a not needed
indirection.  To protect the unaware, just fixed it.

Later, Juan.

Jan Kiszka 8217606e6e Introduce reset notifier order
Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.

Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.

malc 2c44375d64 Do not scare users with ominous error messages from AUD_open*
Apparently Windows Server 2003 sets the frequency for either mc or pi
voice to zero, which in turn triggers a call to audio_bug from this
chain:

open_voice -> AUD_open_in -> audio_bug (audio_validate_settings):

A bug was just triggered in AUD_open_in
...
Context:
audio: frequency=0 nchannels=2 fmt=S16 endianness=little

But since no attempt by the said OS is made to actually use the voice
with zero frequency this can be considered normal behavior.

Hence if zero freqency situation is encountered - close current voice,
and make noises if the guest tries to use it.
