Subject: mm-mlock-refactor-mlock-munlock-and-munlockall-code-v7
Extending the mlock system call is very difficult because it currently
does not take a flags argument. A later patch in this set will extend
mlock to support a middle ground between pages that are locked and
faulted in immediately and unlocked pages. To pave the way for the new
system call, the code needs some reorganization so that all the actual
entry point handles is checking input and translating to VMA flags.
