KVM-87 compile failed

Hi,

Compiling KVM-87 failed with following error:

make -C /lib/modules/2.6.29-gentoo-r5/build M=`pwd` \

GCC-4.3.2-r3, kernel 2.6.29-gentoo-r5.

Compiling worked fine with KVM-86.

I got the same error on Ubuntu 9.04 (2.6.28-11-generic). Debian 5
(2.6.26-2-amd64) works.

kvm-87 is fairly compile-broken on 32-bit hosts.  I need to improve my 
compile testing infrastructure, or make the kvm-xx release candidate 
process public.

You can work around it by replacing 'boot_cpu_data.x86_phys_bits' in 
vmx.c by the constant 40.
