The simple reason for keeping this functionality in KVM, is that it already
has a mature, production-level page walker (which is already exposed) and
creating something similar QEMU would take a lot longer and would be much
harder to maintain than just creating an API that leverages the existing
walker.

ps: this is also a gentle ping for review, if this got lost in between
