>Description:
I think there should be a manpage entry for lwp_trampoline(9).  My understanding is that proc_trampoline was replaced by lwp_trampoline.

It looks like these all point to the same man page of share/man/man9/cpu_lwp_fork(9) :
 cpu_lwp_fork
 child_return
 proc_trampoline

There are references to "proc_trampoline" in these files:
 src/share/man/man9/cpu_lwp_fork.9
 src/share/man/man9/Makefile
 src/distrib/sets/lists/comp/mi

"man lwp_trampoline" should at least point to the same manpage, and possibly replace all references to "proc_trampoline" with "lwp_trampoline" in cpu_lwp_fork.9, or at least make a note about proc_trampoline being obsolete.
>How-To-Repeat:
man lwp_trampoline
>Fix:
Add manpage for lwp_trampoline
