register_savevm(NULL, "cpu", cpu_index, CPU_SAVE_VERSION,

CPU_SAVE_VERSION is defined as 3 in target-mips/cpu.h.
fulong2e instantiates one CPU, so its cpu_index is 0.
Thus the two are fully identical.

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.

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.

scsi_cmd_xfer_mode() is used to specify the xfer direction for SCSI
commands that come in from the guest. If the direction is set incorrectly
this will eventually cause QEMU to kernel-panic the guest.
Add UNMAP and ATAPASSTHROUGH as commands that send data to the device.
Without this change, recent kernels will send both UNMAP as well
as ATAPASSTHROUGH commands to any /dev/sg* device, which due to the
incorrect xfer direction very quickly causes the guest kernel to crash.
Example causing a crash without the patch applied:
./x86_64-softmmu/qemu-system-x86_64 -m 1024 -enable-kvm -cdrom linuxmint-12-gnome-dvd-64bit.iso -drive file=/dev/sg4,if=scsi,bus=0,unit=6

The patch fixes this by making scsi_do_read look like a combination

scsi_read_data) and an unref (like scsi_flush_complete).
