From: Eric B Munson <emunson@xxxxxxxxxx>
Subject: mm-mlock-add-new-mlock-system-call-v7
With the refactored mlock code, introduce a new system call for mlock.
The new call will allow the user to specify what lock states are being
added. mlock2 is trivial at the moment, but a follow on patch will add a
new mlock state making it useful.
