[Qemu-devel] [PATCH 21/64] PPC: KVM: Add stubs for kvm helper functions |

We have a bunch of helper functions that don't have any stubs for them in case
we don't have CONFIG_KVM enabled. That didn't bite us so far, because gcc can
optimize them out pretty well, but we should really provide them.

v1 -> v2:
- use uint64_t for clockfreq
