[PATCH v4 0/3] restructure memfd code

This is a replacement for "Patch series restructure memfd code, v2" which was previously in mmotm. This previous series incorrectly moved the memfd code out of shemm.c as a separate commit. Please let me know if there are any issues with the way code is restructured/moved in this series.
