If you've carefully read George's replies, a primary aspect is
whether we wouldn't better revert commit f5a32c5b8e
("x86/HVM: differentiate IO/mem resources tracked by ioreq
server"), as with the alternative approach we wouldn't even
need HVMOP_IO_RANGE_WP_MEM afaict. And then the question
you raise would become irrelevant.
The part of the public interface being tools only allows some
freedom in when to do this, but I think it would be a bad idea
to ship 4.7 with this still in if you're not going to pursue this
route.
