The VM state offset is a concept internal to the image format. Replace
the old bdrv_{get,put}_buffer method that require an index into the
image file that is constructed from the VM state offset and an offset
into the vmstate with the bdrv_{load,save}_vmstate that just take an
offset into the VM state.

We're marking the used entry bitmap in smbios_load_external() for each
type we check, regardless of whether we loaded anything. This makes
subsequent calls behave as if we've already loaded the tables from qemu
and can result in missing tables (ex. multiple type4 entries on an SMP
guest). Only mark the bitmap if we actually load something.

This allows to set segment registers via gdb also in system emulation
mode. Basic sanity checks are applied and nothing is changed if they
fail. But screwing up the target via this interface will never be
complicated, so I avoided being too paranoid here.

This patch adds support for the vCont remote gdb command. It is used by
gdb 6.8 or better to switch the debugging focus for single-stepping
multi-threaded targets, ie. multi-threaded application in user mode
emulation or VCPUs in system emulation.

This allows to specify an exceptional boot order only for the first
startup of the guest. After reboot, qemu will switch back to the default
order (or what was specified via 'order='). Makes installing from CD
images and then booting the freshly set up harddisk more handy.

This patch changes the boot command line option to the canonical format
-boot [order=drives][,...]
where 'drives' is using the same format as the old -boot. The format
switch allows to add the 'menu' and 'once' options in later patches. The
old format is still understood and will be processed at least for a
transition time.

We're using PCI_CLASS_DISPLAY_OTHER now, but qemu-kvm.git is using
PCI_CLASS_OTHERS because:
"As a PCI_CLASS_DISPLAY_OTHER, it reduces primary display somehow on
Windows XP (possibly Windows disables acceleration since it fails
to find a driver)."
While this is valid, many versions of X will get confused by it.
Class major number of 0 gets treated as a possibly prehistoric VGA
device, and then the autoconfig logic gets confused trying to figure
out whether the virtio console or the pv vga device are the real VGA.
We should really set a proper class ID. 0x0780 (serial / other) seems
most appropriate. This shouldn't require any kernel changes, the
modalias for virtio looks like:
alias: pci:v00001AF4d*sv*sd*bc*sc*i*
so won't care what the base class or subclass are.
It shows up in the guest as:
00:05.0 Communication controller: Qumranet, Inc. Virtio console
A new qdev type is introduced to allow devices using the old class
to be created for compatibility with qemu-0.10.x.

According to PPC440 user manual, PPC 440 supports ``mftb'' even it's a
preserved instruction:
PPC440_UM2013.pdf, p.445, table A-3
when I compile a kernel (2.6.30, bamboo_defconfig/440EP &
canyonlands/460EX), I can see ``mftb'' by using ppc-xxx-objdump
vmlinux
I have also checked the ppc 440x[456], 460S, 464, they also should support mftb.
The following patch enable mftb for all ppc 440 variants, including:
440EP, 440GP, 440x4, 440x5 and 460

The powerpc xml files contained a hack--an empty, non-existent
register--for getting the register numbers to line up for
newer (XML-aware) and older (non-XML-aware) GDB. While this hack worked
in some cases, it didn't work in all cases, notably when the user used
`finish' or `continue': GDB would attempt to read the non-existent
register and QEMU would complain.
This patch fixes things up properly. Instead of inserting a fake
register, we explicitly declare the floating-point and SPE registers to
start at 71. This action accomplishes the same thing as the nasty hack,
except that now GDB never tries to fetch the non-existant register 70.

For 32-bit PPC targets, we translated:
evmergelo rX, rX, rY
as:
rX-lo = rY-lo
rX-hi = rX-lo
which is wrong, because we should be transferring rX-lo first. This
problem is fixed by swapping the order in which we write the parts of
rX.
Similarly, we translated:
evmergelohi rX, rX, rY
as:
rX-lo = rY-hi
rX-hi = rX-lo
In this case, we can't swap the assignment statements, because that
would just cause problems for:
evmergelohi rX, rY, rX
Instead, we detect the first case and save rX-lo in a temporary
variable:
tmp = rX-lo
rX-lo = rY-hi
rX-hi = tmp
These problems don't occur on PPC64 targets because we don't split the
SPE registers into hi/lo parts for such targets.

I now excluded timer interrupt related part.
To my mind other changes are essentially tied together.

Thanks, that part I did not runtime-tested.
Not sure if those asi stores are of any use for user-mode emulator.
