On the other hand, I have no idea what you try to say.

Reviewing this once more:

References within the address range starting at pa and continuing for
len bytes:
range = {pa ... pa+len};

To whole pages following the end of an object:
range = {pa ... PAGE_ROUND_UP(pa+len)};

shall result in delivery of a SIGBUS signal:
pa[ range[n] ]; => SIGBUS


This is clearly not what is meant
