mm/mremap: clean up mlock populate behaviour
When an mlock()'d VMA is expanded, we need to populate the expanded region
to maintain the contract that all mlock()'d memory is present (albeit -
with some period after mmap unlock where the expanded part of the mapping
remains unfaulted).
The current implementation is very unclear, so make it absolutely explicit
under what circumstances we do this.
