Andrew,

I have an updated set that addresses the build failures by completing
the system call additions.  It does not yet address Jon's concern
about applying MLOCK_ONFAULT to a region with pages that are already
present (this is in progress).

Do you want the updated syscalls now or wait until the whole thing is
ready?

IIUC, this should be 391.
