You're passing 'geom->aperture_end - 1' as the size here, but the old code
seemed to _add_ 1:

-	win_size = (domain->geometry.aperture_end + 1) >> ilog2(1);

here ^^ when calculating the exclusive upper bound. In other words, I think
'1ULL << 36' used to get passed to pamu_config_ppaace(). Is that an
intentional change?

No, I've fixed it up.
