Describing the context through a type is much clearer, and good enough
for our case.

We have:
* smaps handling for showing "THPeligible"
* Pagefault handling
* khugepaged handling
* Forced collapse handling: primarily MADV_COLLAPSE, but one other odd case

Really, we want to ignore sysfs only when we are forcing a collapse
through MADV_COLLAPSE, otherwise we want to enforce.

With this change, we immediately know if we are in the forced collapse
case, which will be valuable next.

Nit: if you forward patches untouched, make sure to add your SOB as well.
