Done with this script:
cd hw

echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,'
done | sed -i -f - `find . -type f`
This is so that paths remain valid as files are moved.
Instead, files in hw/dataplane are referenced with the relative path.
We know they are not going to move to include/, and they are the only
include files that are in subdirectories _and_ move.

Since 39bffca203 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.
Fix the documented QOM examples:
sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h
Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c
This also avoids to piggy-back these changes onto real functional
changes or other refactorings.

The Linux ac97 drivers does a number of register read/write tests to
see how much resolution a volume control actually has.
This patch takes this into account by masking out any bits written to
a volume control reg which should not be there according to the spec.
After this the Linux ac97 driver correctly uses a range of 0 - 0x1f for
the PCM out volume, as stated in the spec, and we can fix the FIXME
in update_combined_volume_out().
This patch was also tested with a Windows XP guest without any issues.

After commit 19677a380a:
"hw/ac97: add support for volume control"
We are (correctly) using AC97_Record_Gain_Mute and not AC97_Line_In_Volume_Mute
for recording volume, but various places in hw/ac97 were still assumimg that
we are using AC97_Line_In_Volume_Mute for record volume control, this patch
fixes this.

The Linux ac97 driver tries to see if optional things like video input
volume control are available in 2 ways:
1) See if the mute bit is set after reset, if it is no further tests are done
2) If the mute bit is not set it does a write/read test of the mute bit
This patch changes our ac97 to conform to what the Linux driver expects, it
initializes registers for things which we don't emulate to 0 (so the mute bit
is not set) and makes them read only.
This causes Linux to now longer show the following (functionless)
controls in alsamixer:
Master Mono vol + mute
3d Control toggle
PCM out pre / post 3d select
Surround toggle
CD vol + mute
Mic vol + mute
Mic boost toggle
Mic mic1 / mic2 select
Video vol + mute
Phone vol + mute
Beep mono vol + mute
Aux vol + mute
Mono "output mic" / "mix" select
Sigmatel 4 speaker stereo toggle
Sigmatel ADC 6Db att toggle
Sigmatel DAC 6Db att toggle
This patch was also tested with a Windows XP guest and there it also makes
a number of functionless mixer controls go away.

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.
The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.
We are almost fully converted to QOM after this commit.

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.

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.
