1ddda5cd36 AppleSMC device emulation
Intel Macs have a chip called the "AppleSMC" which they use to control
certain Apple specific parts of the hardware, like the keyboard background
light.

That chip is also used to store a key that Mac OS X uses to decrypt binaries.

This patch adds emulation for that chip, so we're getting one step further
to having Mac OS X run natively on Qemu.

6eab3de16d pci: set PCI multi-function bit appropriately.
Set PCI multi-function bit according to multifunction property.
PCI address, devfn ,is exported to users as addr property,
so users can populate pci function(PCIDevice in qemu)
at arbitrary devfn.
It means each function(PCIDevice) don't know whether pci device
(PCIDevice[8]) is multi function or not.
So this patch allows user to set multifunction bit via property
and checks whether multifunction bit is set correctly.

c0897e0cb9 pc: Fix CMOS info for drives defined with -device
Drives defined with -drive if=ide get get created along with the IDE
controller, inside machine->init().  That's before cmos_init().
Drives defined with -device get created during generic device init.
That's after cmos_init().  Because of that, CMOS has no information on
them (type, geometry, translation).  Older versions of Windows such as
XP reportedly choke on that.

Split off the part of CMOS initialization that needs to know about
-device devices, and turn it into a reset handler, so it runs after
device creation.

7d0d69509a block: Fix virtual media change for if=none
BlockDriverState member removable controls whether virtual media
change (monitor commands change, eject) is allowed.  It is set when
the "type hint" is BDRV_TYPE_CDROM or BDRV_TYPE_FLOPPY.

The type hint is only set by drive_init().  It sets BDRV_TYPE_FLOPPY
for if=floppy.  It sets BDRV_TYPE_CDROM for media=cdrom and if=ide,
scsi, xen, or none.

if=ide and if=scsi work, because the type hint makes it a CD-ROM.
if=xen likewise, I think.

For the same reason, if=none works when it's used by ide-drive or
scsi-disk.  For other guest devices, there are problems:

* fdc: you can't change virtual media

    $ qemu [...] -drive if=none,id=foo,... -global isa-fdc.driveA=foo
    QEMU 0.12.50 monitor - type 'help' for more information
    (qemu) eject foo
    Device 'foo' is not removable

  unless you add media=cdrom, but that makes it readonly.

* virtio: if you add media=cdrom, you can change virtual media.  If
  you eject, the guest gets I/O errors.  If you change, the guest sees
  the drive's contents suddenly change.

* scsi-generic: if you add media=cdrom, you can change virtual media.
  I didn't test what that does to the guest or the physical device,
  but it can't be pretty.

f8b6cc0070 qdev: Decouple qdev_prop_drive from DriveInfo
Make the property point to BlockDriverState, cutting out the DriveInfo
middleman.  This prepares the ground for block devices that don't have
a DriveInfo.

Currently all user-defined ones have a DriveInfo, because the only way
to define one is -drive & friends (they go through drive_init()).
DriveInfo is closely tied to -drive, and like -drive, it mixes
information about host and guest part of the block device.  I'm
working towards a new way to define block devices, with clean
host/guest separation, and I need to get DriveInfo out of the way for
that.

Fortunately, the device models are perfectly happy with
BlockDriverState, except for two places: ide_drive_initfn() and
scsi_disk_initfn() need to check the DriveInfo for a serial number set
with legacy -drive serial=...  Use drive_get_by_blockdev() there.

Device model code should now use DriveInfo only when explicitly
dealing with drives defined the old way, i.e. without -device.

14bafc5407 blockdev: Clean up automatic drive deletion
We automatically delete blockdev host parts on unplug of the guest
device.  Too much magic, but we can't change that now.

The delete happens early in the guest device teardown, before the
connection to the host part is severed.  Thus, the guest part's
pointer to the host part dangles for a brief time.  No actual harm
comes from this, but we'll catch such dangling pointers a few commits
down the road.  Clean up the dangling pointers by delaying the
automatic deletion until the guest part's pointer is gone.

Device usb-storage deliberately makes two qdev properties refer to the
same drive, because it automatically creates a second device.  Again,
too much magic we can't change now.  Multiple references worked okay
before, but now free_drive() dies for the second one.  Zap the extra
reference.

d1d74664ea lsi53c895a: fix Phase Mismatch Jump
lsi_bad_phase has a bug in the choice of pmjad1/pmjad2.  This does
not matter with Linux guests because it uses just one routine for
both, but it breaks Windows 64-bit guests.  This is the text
from the spec:

   "[The PMJCTL] bit controls which decision mechanism is used
   when jumping on phase mismatch. When this bit is cleared the
   LSI53C895A will use Phase Mismatch Jump Address 1 (PMJAD1) when
   the WSR bit is cleared and Phase Mismatch Jump Address 2 (PMJAD2)
   when the WSR bit is set.  When this bit is set the LSI53C895A will
   use jump address one (PMJAD1) on data out (data out, command,
   message out) transfers and jump address two (PMJAD2) on data in
   (data in, status, message in) transfers."

Which means:

    CCNTL0.PMJCTL
        0              SCNTL2.WSR = 0             PMJAD1
        0              SCNTL2.WSR = 1             PMJAD2
        1                    out                  PMJAD1
        1                    in                   PMJAD2

In qemu, what you get instead is:

    CCNTL0.PMJCTL
        0                    out                  PMJAD1
        0                    in                   PMJAD2    <<<<<
        1                    out                  PMJAD1
        1                    in                   PMJAD1    <<<<<

Considering that qemu always has SCNTL2.WSR cleared, the two marked cases
(corresponding to phase mismatch on input) are always jumping to the
wrong PMJAD register.  The patch implements the correct semantics.

The MASTER_DISABLE bit (aka mask-all) masks all the interrupts.

According to Sun-4M System Architecture
"The level–15 interrupt sources [...] are maskable with the Interrupt Target
Mask Register. While these interrupts are considered ’non–maskable’ within
the SPARC IU, a mask capability is provided to allow the boot firmware
to establish a basic environment before receiving any level–15 interrupts,
which are non–maskable within SPARC. A mask–all bit is provided to allow
disabling of all external interrupts during change of the CIT."

Mapped mode stores extended attributes in the user space of the extended
attributes. Given that the user space extended attributes are available
to regular files only, special files are created as regular files on the
fileserver and appropriate mode bits are added to the extended attributes.
This method presents all special files and symlinks as regular files on the
fileserver while they are represented as special files on the guest mount.

Implemntation of symlink in mapped security model:

A regular file is created and the link target is written to it.
readlink() reads it back from the file.

On Guest/Client:
lrwxrwxrwx 1 root root 6 2010-05-11 12:20 asymlink -> afile

On Host/Fileserver:
-rw-------. 1 root root 6 2010-05-11 09:20 asymlink
afile

Under passthrough model, it just calls underlying symlink() readlink()
system calls are used.

Under both security models, client user credentials are changed
after the filesystem objec creation.
