The set of patches below add support for loading plan9's a.out
format using the linux builder. This is considerably simpler
than having a seperate builder, shares more code and should
be easier to maintain. Hopefully the original plan9 builder
can go away in the future.
I've been able to test this manually with vm-tools but am
still having some problems (unrelated I think) with xm.

Rationalise x86 CRn guest state into a ctrlreg array in the per-vcpu
context structure. Most noticeably this means the pt_base field has
gone away -- replaced by ctrlreg[3] (CR3). VCPU_guest_stts is also
gone -- it was never arch-independent anyway.

With the patch attached, we can bring up x86_64 domU to the point where
it tries to mount the root fs (see the log below). We are looking at
problems around blkif_connect at this point.

Remove generic 'fast trap' from the Xen public interfaces. Internally
within Xen, we automatically set up direct trap for int 0x80, which is
the only 'fast trap' vector that we ever supported anyway.

Avoid field duplication between vcpu_guest_context and arch_exec_domain
structures. The latter now includes the former as a sub-field.

Split mmu_update() hypercall into mmu_update() and mmuext_op().
All MMUEXT_* ops are now done via the latter hypercall. This allows
more arguments to be passed in a nicer way to mmuext operations.
Linux 2.4, 2.6 and control tools all use the new interface. The BSDs
will need some work, but shouldn't be too hard (and they can be moved
to writable pagetables at the same time :-) ).

[PATCH] [PATCH] gcc4isms part 2
This completes the gcc4ism changes to the Xen tree. All of
the changes in this patch are in the tools/ subdirectory and
are pretty simple. Some of the changes are for overly strict
gcc4 warnings, but I guess it's still good to verify that the
variable really wasn't unused, or that the sign change is
really harmless.
I guess I really do like -Werror now...

x86 ( 32bit) is the only architecture that uses Fast trap vector offset
( fast_trap_idx ). This makes sure that x86 is the only architecture to
use this variable.

Add an optional parameter (vcpus) to the xc_linux_build function replacing
the getenv() previously used and removing the requirement of using maxcpus
kernel parameter to limit the number of virtual cpus a guest uses. The value
can now be controlled in the domain configuration files.
The default value of 1 is set in XenDomainInfo.py but is overridden by
parsing the config value.

The getdomaininfo hypercall now listens to the exec_domain parameter
that was already passed to it, and performs some basic sanity checking.
Added exec_domain (aka vcpu) parameters to xc_domain_getfullinfo()
and xc_domain_get_cpu_usage().
Code duplication cleanup: remove a number of duplicate identical
static functions in xc_*_{build,restore}.c, replaced with single
(non-static) copy in xc_private.c
