There were some missing pieces for trying this patch series.
Firstly, the patch is for v3.5-rc4, but that version has an issue

Hi,

One way to reproduce this is:
qemu-kvm-1.0.1 with vnc-thread enabled
A new module named vmcsinfo-intel is used to fill VMCSINFO. And
this module depends on kvm-intel and kvm module. So we should
export some symbols of kvm-intel and kvm module that are needed
by vmcsinfo-intel.

Allow CROSS_COMPILE to be used to prefix CC as is done in the kernel
Makefile. If CROSS_COMPILE is unset it has no effect, and still allows

We need to fix a few places to use ARCH instead of uname_M directly, so
that the overridden setting of ARCH takes effect.
The sed expression for ARCH seems to have been cribbed from the top-level
kernel Makefile, and includes lots of architectures kvmtool doesn't

Also call uname -m directly there and get rid of uname_M.
