Add a short explanation of what HPA is maybe (or at least expand the 
acronym)?

It's also not obvious (at least not to a dumb user like me) that "ignore 
HPA limit" is equivalent to "preserving the Host Protected Area" as the 
commit commit says.
After reading the wiki page on HPA it looks like the actual meaning is to
"make the HPA visible to the OS"?

Hmm. This looks weird. Is "BIOS limits" a synonym for "HPA limit"?
Same goes for the MODULE_PARM_DESC.
