KVM: ppc: PowerPC 440 KVM implementation

Browse Source 
This functionality is definitely experimental, but is capable of running
unmodified PowerPC 440 Linux kernels as guests on a PowerPC 440 host. (Only
tested with 440EP "Bamboo" guests so far, but with appropriate userspace
support other SoC/board combinations should work.)

See Documentation/powerpc/kvm_440.txt for technical details.

Say Y to enable some early debugging facilities that may be available
for your processor/board combination. Those facilities are hacks
