8be7e7e4c7 qemu-option: qemu_opts_create(): use error_set()
This commit converts qemu_opts_create() from qerror_report() to
error_set().

Currently, most calls to qemu_opts_create() can't fail, so most
callers don't need any changes.

The two cases where code checks for qemu_opts_create() erros are:

 1. Initialization code in vl.c. All of them print their own
    error messages directly to stderr, no need to pass the Error
    object

 2. The functions opts_parse(), qemu_opts_from_qdict() and
    qemu_chr_parse_compat() make use of the error information and
    they can be called from HMP or QMP. In this case, to allow for
    incremental conversion, we propagate the error up using
    qerror_report_err(), which keeps the QError semantics

9c92bf7f6c Revert "rtl8139: do the network/host communication only in normal operating mode"
This reverts commit ff71f2e8ca. This is because
the linux 8139cp driver would leave the card in "Config Register Write Enable"
mode after the eeprom were read or write ( which is unexpected in the spec
). Also a physical 8139 card can still DMA into host memory in modes other than
Normal mode, so we need revert this commit to align with the behavior of
physical card.

The issue of 8139cp driver should be fixed in linux seperately.

136be99e6e virtio-blk: Fix geometry sector calculation
Currently the sector value for the geometry is masked, even if the
user usesa command line parameter that explicitely gives a number.
This breaks dasd devices on s390. A dasd device can have
a physical block size of 4096 (== same for logical block size)
and a typcial geometry of 15 heads and 12 sectors per cyl.
The ibm partition detection relies on a correct geometry
reported by the device. Unfortunately the current code changes
12 to 8. This would be necessary if the total size is
not a multiple of logical sector size,  but for dasd this
is not the case.

This patch checks the device size and only applies sector
mask if necessary.

a6de8ed80e pci: call object_unparent() before free_qdev()
Start VM with 8 multiple-function block devs, hot-removing
those block devs by 'device_del ...' would cause qemu abort.

| (qemu) device_del virti0-0-0
| (qemu) **
|ERROR:qom/object.c:389:object_delete: assertion failed: (obj->ref == 0)

It's a regression introduced by commit 57c9fafe

The whole PCI slot should be removed once. Currently only one func
is cleaned in pci_unplug_device(), if you try to remove a single
func by monitor cmd.

free_qdev() are called for all functions in slot,
but unparent_delete() is only called for one
function.

9c3a596a03 fix multiboot loading if load_end_addr == 0
The previous multiboot load code did not treat the case where
load_end_addr was 0 specially.  The multiboot specification says the
following:
 * load_end_addr
   Contains the physical address of the end of the data segment.
   (load_end_addr - load_addr) specifies how much data to load. This
   implies that the text and data segments must be consecutive in the
   OS image; this is true for existing a.out executable formats. If
   this field is zero, the boot loader assumes that the text and data
   segments occupy the whole OS image file.

cfb08fbafc fdc: fix media detection
We have to set up 'media_changed' after guest start so floppy driver
could detect that there is no media in drive. For this purpose we call
'fdctrl_change_cb' instead of 'fd_revalidate' in 'fdctrl_connect_drives'.
'fd_revalidate' is called inside 'fdctrl_change_cb'.

We still have to set default drive geometry in 'fd_revalidate' even
if there is no media in drive. When you try to open (windows) or mount (linux)
floppy the driver tries to seek on track 1. Linux guest stuck in loop then
kernel crashes and windows guest prints error message.

a6c5c84ae2 virtio-blk: always enable VIRTIO_BLK_F_SCSI
VIRTIO_BLK_F_SCSI is supposed to mean whether the host can *parse*
SCSI requests, not *execute* them.  You could run QEMU with scsi=on
and a file-backed disk, and QEMU would fail all SCSI requests even
though it advertises VIRTIO_BLK_F_SCSI.

Because we need to do this to fix a migration compatibility problem
related to how QEMU is invoked by management, we must do this
unconditionally even on older machine types.  This more or less assumes
that no one ever invoked QEMU with scsi=off.

Here is how testing goes:

- old QEMU, scsi=on -> new QEMU, scsi=on
- new QEMU, scsi=on -> old QEMU, scsi=on
- old QEMU, scsi=off -> new QEMU, scsi=on
- new QEMU, scsi=off -> old QEMU, scsi=on
        ok (new QEMU has VIRTIO_BLK_F_SCSI, adding host features is fine)

- old QEMU, scsi=off -> new QEMU, scsi=off
        ok (new QEMU has VIRTIO_BLK_F_SCSI, adding host features is fine)

- old QEMU, scsi=on -> new QEMU, scsi=off
        ok, bug fixed

- new QEMU, scsi=on -> old QEMU, scsi=off
        doesn't work (same as: old QEMU, scsi=on -> old QEMU, scsi=off)

- new QEMU, scsi=off -> old QEMU, scsi=off

f34e73cd69 virtio-blk: report non-zero status when failing SG_IO requests
Linux really looks only at scsi->errors for SG_IO requests; it does
not look at the virtio request status at all.  Because of this, when
a SG_IO request is failed early with virtio_blk_req_complete(req,
VIRTIO_BLK_S_UNSUPP), without writing hdr.status, it will look like
a success to the guest.

This is their bug, but we can make it safe for older guests now by
forcing scsi->errors to have a non-zero value whenever a request
has to be failed.

But if we fix the bug in the guest driver, we will have another problem
because QEMU returns VIRTIO_BLK_S_IOERR if the status is non-zero, and
Linux translates that to -EIO.  Rather, the guest should succeed the
request and pass the non-zero status via the userspace-provided SG_IO
structure.  So, remove the case where virtio_blk_handle_scsi can
return VIRTIO_BLK_S_IOERR.

2cdfe53c5f msix: Introduce vector notifiers
Vector notifiers shall be triggered by the MSI/MSI-X core whenever a
relevant configuration change is programmed by the guest. In case of
MSI-X, changes are reported when the effective mask (global &&
per-vector) alters its state. On unmask, the current vector
configuration is included in the event report. This allows users - e.g.
virtio-pci layer - to transfer this information to external MSI-X
routing subsystems - like vhost + KVM in-kernel irqchip.

This implementation only provides MSI-X support, but extension to MSI is
feasible and will be provided later on when adding support for KVM PCI
device assignment.

0c9dfe460d mips_fulong2e: Don't register "cpu" VMState twice
We have the following simplified callgraph in mips_fulong2e_init():

  cpu_init() => cpu_mips_init()
    object_new()
      mips_cpu_initfn()
        cpu_exec_init()
          register_savevm(NULL, "cpu", cpu_index, CPU_SAVE_VERSION,
                          cpu_save, cpu_load, env)
  register_savevm(NULL, "cpu", 0, 3, cpu_save, cpu_load, env)

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.

Therefore just remove the second call in fulong2e.

bdc62e62ea rtl8139: fix regression in TxStatus/TxAddr read
Commit afe0a59535 added byte reads for TxStatus/TxAddr, but
broke 32-bit reads; the mask generation

   (1 << (8 * size)) - 1

is unspecified in C for size >= sizeof(int), and in fact returns 0
on x86.

Fix by using a larger type.

Fixes (at least) Fedora 9 i386 with -machine kernel_irqchip=on.  I
didn't see it with the qemu APIC implementation; may be due to timing
or (more likely) a tester error.

7873bfb866 hw/ac97: Mask out unused bits of volume controls
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.

d044be3714 hw/ac97: Make a bunch of mixer registers read only
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.

381b634c27 scsi: Specify the xfer direction for UNMAP and ATA_PASSTHROUGH commands
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 reason is that WIN_SECURITY_FREEZE_LOCK / CFA_WEAR_LEVEL is not
supported by our ATA implementation, but Windows expects it to be there.

Since without security stuff implemented, the lock would be a nop anyway
and CFA_WEAR_LEVEL already is treated as a nop, let's just allow the cmd
