Where did KVM go in 2.6.22-git9?

Where did KVM go in 2.6.22-git9?

[Bill Davidsen]

I just built a 2.6.22-git9 kernel, and when I run oldconfig it (a) sets 
the processor type to pentium-pro, and (b) the KVM stuff simply isn't in 
the config. Before I spend a lot of time on this, was it disabled 
temporarily for some reason, or is it a known bug, or ???

Processor is a Core2 E6600, and the starting config has KVM.

Strong suggestion: put KVM in processor type and options, and if the CPU 
type selected supports the feature, let the builder turn it on in one 
place and have Kconfig turn on whatever voodoo is needed to allow it, 
rather than have people trying to find out what depends have changed 
with each release. I see KVm depends on X86_CMPXCHG64 which simply 
doesn't seem to be defined directly anywhere.

Going back to 2.6.21.6 until whatever changed is at least documented.

Kconfig changes got kvm temporarily disabled on i386 nonpae.  Current
-git has it back.
