That makes sense. The reasons why it's an experimental feature is that it contradicts the spec. Some code path in l4test relies on it though. I'll at a catcher to find if pagerexregs is advertised as a kernel feature, and skip the test if not.

It is actually a menuconfig option. You have to enable experimental features in the kernel menu.
