[PATCH] make KVM selectable again

[Dave Hansen]

Current git for me (b1d0e4f535e10775cffde922208b49629169aeaa) doesn't
let me build KVM.  In fact, I don't seem to have *ANY* kvm-related
symbols in my .config at all.

I've verified that arch/x86/kvm/Kconfig was getting run by putting some
comments in it.  It seems to me like just putting:

	config HAVE_KVM
	       bool

isn't letting anything come into my .config at all.  I'm not sure why we
do that, and then have:

	select HAVE_KVM

in arch/x86/Kconfig.

This patch just defines HAVE_KVM in the x86 Kconfig and is done with it.
Seems to work for me.

Was there some reason that it was done this way?  Was it ever tested?
