Subject: [PATCH v3 00/17] Allow changing of Hypervisor CPUIDs.

Also known as Paravirtualization CPUIDs.

This is primarily done so that the guest will think it is running
under vmware when hypervisor-vendor=vmware is specified as a
property of a cpu.


This depends on:

http://lists.gnu.org/archive/html/qemu-devel/2012-09/msg01400.html

As far as I know it is #4. It depends on (1) and (2) and (3).

This change is based on:

Microsoft Hypervisor CPUID Leaves:
http://msdn.microsoft.com/en-us/library/windows/hardware/ff542428%28v=vs.85%29.aspx

Linux kernel change starts with:
http://fixunix.com/kernel/538707-use-cpuid-communicate-hypervisor.html
Also:
   http://lkml.indiana.edu/hypermail/linux/kernel/1205.0/00100.html

VMware documention on CPUIDs (Mechanisms to determine if software is
running in a VMware virtual machine):
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1009458

Changes from v1 to v2:

1) Added 1/4 from 
http://lists.gnu.org/archive/html/qemu-devel/2012-08/msg05153.html

    Because Fred is changing jobs and so will not be pushing to get
    this in. It needed to be rebased, And I needed it to complete the
    testing of this change.

2) Added 2/4 because of the re-work I needed a way to clear all KVM bits,

3) The rework of v1.  Make it fit into the object model re-work of cpu.c 
for x86.

4) Added 3/4 -- The split out of the code that is not needed for accel=kvm.

Changes from v2 to v3:

Marcelo Tosatti:
   Its one big patch, better split in logically correlated patches
   (with better changelog). This would help reviewers.

So split 3 and 4 into 3 to 17.  More info in change log.
No code change.
