We're now able to hide PMU registers from the guest when no PMU is available, but I just realised that we don't do the same thing for userspace, which is pretty annoying (as it ends up with garbage). The first patch introduces a visibility callback for all PMU regs, which applies to both guest and userspace. That's what I should have done the first place. The second patch is only a cleanup, now that we are doing the right thing. This is a potential fix for 5.11, so shout if you spot something! Thanks, M.
