I don't think there are - contiguous chunks of pages can't have a PDX hole in their middle. There would be two parts (before and after the hole), and no allocation can return two such parts. Furthermore PDX compression actually _reduces_ holes, i.e. there might only be a case where physical addresses are discontiguous yet virtual ones are contiguous, but never the other way around.
