Subject: [PATCH] qemu-kvm: other archs should maintain memory mapping also.
Currently, use TARGET_I386 to comment out the mapping machanism
for other archs, but mapping machanism should be useful for other archs
to maintain guest's memory mapping.
Hollis, does this work for you?
If now, you can add a new define KVM_WANT_MAPPING or something, and
define it for I386 and IA64.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
