When I try to run KVM built off the current head, it crashes with a
Segmentation fault. KVM-84 does
not. Seems to be dealing with the CPUID changes:
0x081a5c70 in host_cpuid ()
at /home/kressb/kvm/src/qemu/target-i386/helper.c:1426
1426 asm volatile("pusha \n\t"
At a guess, it's this commit:
commit b9bacf8975c5db7b6f14cabcae98130913f2d013

KVM: CPUID takes ecx as input value for some functions (Amit Shah)
The CPUID instruction takes the value of ECX as an input parameter
in addition to the value of EAX as the count for functions 4, 0xb
and 0xd. Make sure we pass the value to the instruction.
Also convert to the qemu-style whitespace for the surrounding code.

In case it matters, the host CPU is:
Intel(R) Core(TM)2 CPU 6420 @ 2.13GHz
