Committed 0001.
I also tweaked the notes for both FreeBSD and NetBSD where we mention
kern.ipc.shm_use_phys to clarify that this refers only to System V
shared memory (before this commit, those notes were arguably a bit
misleading).
I noticed in passing that the comments about jails and System V shared
memory are out of date (the key namespace situation changed in FreeBSD
11), but I'll look into that another day.
I've moved the CF entry to the next Commitfest, since we still have to
fix up and commit the 0002 patch for AIX.
