So I've pulled this (not pushed out yet, I've done all the
allmodconfig builds, but I want to reboot into this all too), but I'm
not entirely sure I'm happy about how it enabled MPX support by
default.

Why would I want to enable this in my kernel when there are no actual
CPU's out yet that support it? And even when there are, why would I do
it if the CPU I have doesn't support it?

So I think it needs to be a real config option with a real question,
not a "def_bool" that just depends on "do you want to support Intel
CPU's"
