This has finally bugged me enough to do something about it:
make prints `***' when it stops due to an error. With make -j, and/or
with automated build systems, this error marker can be in the middle
of a large logfile. It is useful to be able to search for it.
Therefore change occurrences of `*' to `=' for information and warning
messages. `***' is reserved for cases where the build stops.
A corresponding change is being applied to qemu-xen-unstable.

If you use -MMD -MF then the correct .o filename is written to the
.*.d file as the compiler driver arranges everything. This was done
in 19010:275abe1c5d24 for the hypervisor.
In this patch we do the same elsewhere in the xen-unstable tree,
particularly tools/. Specifically:
* Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS.
* Remove -Wp,-MD... from every other Makefile
* Remove setting of DEPS from every other Makefile
* Ensure that every Makefile says -include $(DEPS)
* Ensure that every Makefile's clean target removes $(DEPS)
Some Makefiles were already halfway there, but often for a different
variable name eg PROG_DEP. The variable name is now standardised in
Rules.mk as DEPS.
I have done a test build with this change, on Debian etch.

I have copied the tarballs that the xen-unstable build downloads to
xenbits.xensource.com (which also hosts our hg and git). This patch
changes the download URLs to use that location.
That way the build will depend on only one external machine, under one
administration, rather than many. Also it means that the build won't
break if these sites become permanently unavailable or are rearranged
and we don't run a risk of having to panic and beg if a file should go
missing.

In DSDT, reserve the IO port ranges: [0x10c0, 0x10c2] and [0xb044,
0xb047] that are used by the virtual PCI hotplug.
Or else, for a hotplugged-in device, the port IO BAR assigned by guest
OS may conflict with the ranges here.

When a VMX guest tries to enter real mode, put it in virtual 8086 mode
instead, if that's possible. Handle all errors and corner cases by
falling back to the real-mode emulator.
This is similar to the old VMXASSIST system except it uses Xen's
x86_emulate emulator instead of having a partial emulator in the guest
firmware. It more than doubles the speed of real-mode operation on
VMX.

BIOS. Current Xen hard coded VGA ROM at 0xC0000 and etherboot ROM
at 0xD0000. This makes the space in [0xC0000 - 0xDFFFF] to be
fragments, which makes it hard to find enough space to hold another
Option ROM.

When creating an HVM domain, if e.g. another domain is created before
qemu allocates video memory, the extra 8MB memory ballooning is not
available any more, because it got consumed by the other domain.
This fixes it by taking video memory from the main memory:
- make hvmloader use e820_malloc to reserve some of the main memory
and notify ioemu of its address through the Xen platform PCI card.
- add XENMAPSPACE_mfn to the xen_add_to_physmap memory op, to allow
ioemu to move the MFNs between the original position and the PCI
mapping, when LFB acceleration is disabled/enabled
- add a remove_from_physmap memory op, to allow ioemu to unmap it
completely for the case of old guests with acceleration disabled.
- add xc_domain_memory_translate_gpfn_list to libxc to allow ioemu to
get the MFNs of the video memory.
- have xend save the PCI memory space instead of ioemu: if a memory
page is there, the guest can access it like usual memory, so xend
can safely be responsible to save it. The extra benefit is that
live migration will apply the logdirty optimization there too.
- handle old saved images, populating the video memory from ioemu if
really needed.
