Why do you think they rely on it being static? The VSYSCALL address is
not changed for example.

I don't know, that's why I'm asking first. Userspace is known to pick
different aspects of the kernel and deciding to use them for whatever.
And once it relies on that, there's no changing it.

Ok, so we should be fine here because those addresses are internal to
the kernel, I'm being told, so anything using them will break and gets
to keep the pieces even.
