pmap_remove() would be called with a huge range and we'd stride across it in only 2MB chunks. This would manifest as massive cpu time and a largely unresponsive system during hard swap. Instead, check the higher page directories which means we can run pmap_remove() in just a few hundred loop iterations instead of millions since we can process address space in chunks of 512GB and 1GB as well as 2MB.
