ksm was deliberately made independent of kvm. While there may or may
not be uses of ksm without kvm (you could run ordinary qemu, but no one
would do this in a production deployment), keeping them separate helps
avoid unnecessary interdependencies. For example all tlb flushes are
mediated through mmu notifiers instead of ksm hooking directly into kvm.
