Put all arch-specific files into arch/ia64/kvm as you described in
future KVM infrastructure.

It may work on x86 side. But for IA64, we have several source files and
assembly files to implement a VMM module, which contains the
virtualization logic of CPU, MMU and other platform devices. (In KVM
forum, Anthony had presented IA64/KVM architecture which is a bit
different with x86 side due to different approaches for VT.).If we put
all such these arch-specific files in one directory, it looks very
strange!
