Just to clarify, "the rest" refers to hypercalls made from the kernel,
correct? Any hypercall using VAs made from user space are at issue here.

I agree, why create a new mapping when a usable one exists.
At least for common kernel code, we will need to wrap such VAs in a
macro so that the "psuedo-physical" is passed in for PPC. I assume
this is reasonable?
