Re: [mm PATCH v5 0/7] Deferred page init improvements

This patchset is essentially a refactor of the page initialization logic that is meant to provide for better code reuse while providing a significant improvement in deferred page initialization performance. In my testing on an x86_64 system with 384GB of RAM and 3TB of persistent memory per node I have seen the following. In the case of regular memory initialization the deferred init time was decreased from 3.75s to 1.06s on average. For the persistent memory the initialization time dropped from 24.17s to 19.12s on average. This amounts to a 253% improvement for the deferred memory initialization performance, and a 26% improvement in the persistent memory initialization performance.
