As noted in [1] the KVM_GUEST_USES_PFN usage flag is never set by any
callers of kvm_gpc_init(), which also makes the 'vcpu' argument redundant.
The changelog should explicitly call out that not only is KVM_GUEST_USES_PFN
unused, it's incomplete/broken (which is also partly why it's unused). Without
that information, removing the support looks like a somewhat arbitrary decision,
versus a deliberate change to make it easier to support the gpc code.
Ok. I'll add some words to that effect.
