It's perfectly fine to do things one bit at a time. In this case,
cr4_init() is does two different things underneath the covers depending
on the state of CR pinning. If CR pinning as a feature is kicked out
influencing the early CPU boot code at _all_, then it certainly helps
the goal if making the AP/BSP code more symmetric.

So I very much prefer doing things one bit at a time, if we can.
