The one hunk involving tf_rip and PS_STRINGS in amd64 looks to be unrelated.
Also, in subr_param.c, you can assume that MSGBUF_SIZE is always defined
and always assign it as the initial value rather than having an #ifdef.
Finally, I would adjust the wording in the manpage to not say that this
modifies the MSGBUF_SIZE option, but that this tunable is the same as
adjusting MSGBUF_SIZE.  Other than that I think it is fine.
