[Qemu-devel] [PATCH v3 00/17] Allow changing of Hypervisor CPUIDs.

[Don Slutz]

Resend with new id so the backup files are not included.

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:

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.
