Implement device tree support needed for Bamboo emulation
To implement the -kernel, -initrd, and -append options, 4xx board emulation
must load the guest kernel as if firmware had loaded it. Where u-boot would be
the firmware, we must load the flat device tree into memory and set key fields
such as /chosen/bootargs.
This patch introduces a dependency on libfdt for flat device tree support.

target-ppc: create a helper function to allow more flexible RAM allocation for PPC 4xx
The 4xx SDRAM controller supports a small number of banks, and each bank must
be one of a small set of sizes. The number of banks and the supported sizes
varies by SoC.
This function uses the user-specified RAM size to fill in the "ram_bases" and
"ram_sizes" arrays required by ppc4xx_sdram_init().

target-i386: SVM: acknowledge interrupt only after it is taken
SVM specifies that the V_IRQ mask is only to be removed, if the
interrupt that is to be delivered actually is delivered.
As of the SVM rewrite, this mask is always unmasked when the main cpu
loop is processed, leaving a corner case where calling the interrupt
handler causes a #PF. In that case (booting Linux / starting gfxboot)
the current implementation tells the VMM the interrupt is taken, even
though it is not.
This patch modifies the VIRQ unmasking to occur after do_interrupt,
making gfxboot work again.

Replace posix-aio with custom thread pool
glibc implements posix-aio as a thread pool and imposes a number of limitations.
1) it limits one request per-file descriptor. we hack around this by dup()'ing
file descriptors which is hideously ugly
2) it's impossible to add new interfaces and we need a vectored read/write
operation to properly support a zero-copy API.
What has been suggested to me by glibc folks, is to implement whatever new
interfaces we want and then it can eventually be proposed for standardization.
This requires that we implement our own posix-aio implementation though.
This patch implements posix-aio using pthreads. It immediately eliminates the
need for fd pooling.
It performs at least as well as the current posix-aio code (in some
circumstances, even better).

pci: add default pci subsystem id for all devices (Gerd Hoffman)
This sets a default PCI subsystem ID for all emulated PCI devices. PCI
specs require this, so do it.
In many cases it is enougth to know the PCI ID to handle a device
correctly. Sometimes a device driver must identify the exact piece of
hardware (via PCI Subsystem ID) though.
What does this patch to qemu devices:
Right now the emulated PCI devices have no PCI subsystem ID, only the
PCI ID. The discussed patch sets a default PCI subsystem ID for all
emulated devices. Which will make the qemu devices look pretty much
like in the laptop case: all PCI subsystem IDs will point to qemu by
default.
If a driver emulates a very specific piece of hardware where it has to
emulate more than just the PCI chip, it can overwrite the PCI subsystem
ID without problems. The es1370 driver does that for example.

Fix handling of disk-only snapshots (Kevin Wolf)
When creating a snapshot with multiple qcow2 disks attached, the current
behaviour is that qemu creates a disk snapshot on all of them and
chooses one to write the VM state to.
Despite having the state only in one image, loadvm tries to restore the
VM state from the middle of nowhere if you run qemu a second time with
only one of the other images attached. In the lucky case it will fail
because there simply is no state, but it also can happen that it loads
the state of a different snapshot (the one this new one is based upon).
The fix is to write a zero VM state size to the images which don't
contain the state, and check this in loadvm.
I agree that you probably have to provoke such things intentionally to
get in a state like this with qemu itself. However, with my second patch
that adds snapshot support to qemu-img it could become a reasonable use
case to have snapshots with and without VM states on the same image.

Add 64-bit Block Move support (Direct & Table Indirect) (Ryan Harper)
This patch adds support for 64-bit Block Move instructions. There are multiple
modes for 64-bit Block moves, direct, indirect, and table indirect. This patch
implements Direct and Table indirect moves which are needed by 64-bit windows
and SYM_CONF_DMA_ADDRESSING_MODE=2 for the Linux sym53c8xx_2 driver respectively.
Two helper functions are included to check which mode the guest is using. For
64-bit direct moves, we fetch a 3rd DWORD and store the value in the DBMS
register. For Table Indirect moves, we look into the table for which register
contains the upper 32-bits of the 64-bit address. This selector value indicates
which register to pull the value from and into dnad64 register.
Finally, lsi_do_dma is updated to use the approriate register to build a 64-bit
DMA address if required.
With this patch, Windows XP x64, 2003 SP2 x64, can now install to scsi devices.
Linux SYM_CONF_DMA_ADDRESSING_MODE=2 need a quirk fixup in Patch 4 to function
properly.

Accept password as an argument to 'change vnc password' monitor command (Chris Webb)
This allows easier use of the change vnc password monitor command from
management scripts, without having to implement expect(1)-like behaviour.

Fix off-by-one bug limiting VNC passwords to 7 chars (Chris Webb)
monitor_readline expects buf_size to include the terminating \0, but
do_change_vnc in monitor.c calls it as though it doesn't. The other site
where monitor_readline reads a password (in vl.c) passes the buffer
length
correctly.
