Currently, the msrs involved in setting up pvclock are not saved over

kvm also has to account for it, by including them in the msr list

vnc: fix capslock tracking logic.
The capslock tracking logic added by commit 6b1325029d80455b9da7cd7bd84a88cb915b867c doesn't work correctly for vnc
clients without EXT_KEY_EVENT support. The reason is that qemu converts
keysyms for letters to lowercase for the keysym2scancode lookup. It
then also passes the lowercase value down to do_key_event(), but the
capslock tracking code needs it with the correct case to work properly.
This patch adds a new variable for the lowercase keysym so we'll keep
the unmodified value for do_key_event().
The keysym2scancode is not needed with EXT_KEY_EVENT capable clients
like any app based on the gtk-vnc widget, so I missed that case in
testing ...

cpuid: Fix multicore setup on Intel
The multicore CPUID code detects whether the guest is an Intel or an

KVM by default passes through the host's vendor, which was not

separate function to be used from both places and always get the real

This fixes KVM's multicore setup on Intel CPUs.

kvm: x86: Fix initial kvm_has_msr_star
KVM_GET_MSR_INDEX_LIST returns -E2BIG when the provided space is too
small for all MSRs. But this is precisely the error we trigger with the
initial request in order to obtain that size. Do not fail in that case.
This caused a subtle corruption of the guest state as MSR_STAR was not
properly saved/restored. The corruption became visible with latest kvm
optimizing the MSR updates.

Add S390 maintainer information
This patch adds information about who handles what when it comes to S390.
I'll gladly support anything that's related to the device emulation model and
S390 KVM parts.
Since this patchset doesn't implement S390 CPU emulation, I left that part
with a question mark. As soon as Uli's patchset gets committed I'd recommend
setting him there.

Set default console to virtio on S390x
All "normal" system emulation targets in qemu I'm aware of display output
on either VGA or serial output.
Our S390x virtio machine doesn't have such kind of legacy hardware. So
instead we need to default to a virtio console.
I'm not particularly proud of this patch. It would be a lot better to
have something in the machine description that tells us about the default
terminal.

Add S390x virtio machine description
In order to use the new S390x virtio bus we just introduced, we also
need a machine description that sets up the machine according to our
PV specification.
Let's add that machine description and be happy!

Add KVM support for S390x
S390x was one of the first platforms that received support for KVM back in the
day. Unfortunately until now there hasn't been a qemu implementation that would
enable users to actually run guests.
So let's include support for KVM S390x in qemu!

S/390 fake TCG implementation
Qemu won't let us run a KVM target without having host TCG support. Well, for
now we don't have any so let's implement a fake target that only stubs out
everything.
I tried to keep the patch as close to Uli's source as possible, so whenever
he feels like it he can easily diff his version against this one.

S/390 CPU fake emulation
Because Qemu currently requires a TCG target to exist and there are quite some
useful helpers here to lay the groundwork for out KVM target, let's create a
stub TCG emulation target for S390X CPUs.
This is required to make tcg happy. The emulation target itself won't work
though.
