Summary

we have a repeat of kern.elf32.aslr.aslr_stack_gap here; This patch fixes it.

Test Plan

make
man ./security.7.gz

However,

mandoc -Tlint reports:

mandoc: security.7:234:6: STYLE: referenced manual not found: Xr ksu 1
mandoc: security.7:314:6: STYLE: referenced manual not found: Xr imapd 8 (2 times)

I believe these oids need updating as well:

$ uname -msr
FreeBSD 13.0-CURRENT amd64
$ sysctl kern.elf{32,64}.aslr.aslr_stack_gap
sysctl: unknown oid 'kern.elf32.aslr.aslr_stack_gap'
sysctl: unknown oid 'kern.elf64.aslr.aslr_stack_gap'
$ sysctl kern.elf{32,64}.aslr.stack_gap
