[Qemu-devel] [PATCH v7 17/17] target-i386: target-i386: Add VMWare CPUID Timing information in -machine pc, accel=tcg |

Part of "target-i386: Add way to expose VMWare CPUID"
This is EAX and EBX data for 0x40000010.
Add new #define CPUID_HV_TIMING_INFO for this.
The best documentation I have found is:
http://article.gmane.org/gmane.comp.emulators.kvm.devel/22643
And a test under ESXi 4.0 shows that VMware is setting this data.
