interface, which is used for the virtual interfaces of dom0 instead
of netfront/netback.
I need to issue ethtool -K eth0 tx off to work around a bad checksum
problem, which has been reported for domUs a few months ago. I'm
bridging dom0's eth0 to a domU where I do NAT to a different virtual
interface. Without this change, I get lots of packets with bad
checksums.

a) for namespacing and b) to match up with the other xenstore commands
better.

It doesn't work because we already set VCPUF_running
locally, and the scheduler should not pick another CPU's
VCPUF_running VCPU anyway, since it mustn't modify the
processor field.
Instead just add a simple assertion to the scheduler to
ensure the scheduling algorithm is not picking an
inappropriate VCPU.

changeset. It makes no sense, since an allocated VCPU
cannot be freed at any arbitrary point because individual
VCPUs are not refcounted.
Instead extend free_domain() slightly so it really does do
the reverse of alloc_vcpu() for every allocated VCPU.

Interface name changes:
1. do_createdomain -> domain_create
2. domain_destruct -> domain_destroy
Arch-specific changes:
1. arch_do_createdomain -> arch_domain_create
This function now takes a domain pointer, not a VCPU
pointer! Initialisation of VCPU0 must happen in
alloc_vcpu_struct().
2. free_perdomain_pt -> arch_domain_destroy
This function must undo the work of arch_domain_create
TODO: arch_domain_create() refactoring is not completed
for ia64.

VCPU's context has been explicitly initialised.
Fix all the domain builders to no longer attempt this.
They really don't need to anyhow.

when allocating a new vcpu structure, not copied from
CPU0's idle VCPU. Especially now that the idle VCPU itself
is dynamically allocated.
This should fix assertions people have been seeing in
getdomain_info_ctxt() relation to IOPL in eflags.

If the guest context is VM86 then we need to treat ss:sp as 16 bit
segment:offset rather than 32 bit selector:offset.

the approrpiate per-CPU lock, we must re-check the VCPU's
current CPU binding after the lock is acquired.

Add 'N' keyhandler to dump the current per CPU NMI counts and the
current NMI mask/pending status.
Add 'n' keyhandler to trigger an NMI by sending an IPI. For some
reason the destination shorthand for self is not valid when used with
the NMI delivery mode so we send the IPI to our own APIC ID
explicitly.
