What do you think the maintainers are for? To clean up after
people... ;-\

As a matter of fact, updating the documentation is already on my
ever-growing TODO list.

But for this patch I'd like to ask whoever of you does it, to add a one
or two sentences about why we need to allow STIBP selection with IBRS.

The rest of the documentation we'll flesh out in time.

Thx.
