NAK.

The whole point of this is to eliminate the need for vmware detection,
which is something the kernel shouldn't need to know about.
Instead VMware should supply that bit by itself and then Linux could
do the right thing. The only change you would need to do is to always
check it for all CPU vendors, not just AMD.
Adding it with vmware detection code is not useful.
