Module Name:    src
Committed By:   christos

Modified Files:
        src/share/man/man7: sysctl.7
        src/sys/dev: mm.c
        src/sys/kern: init_sysctl.c kern_proc.c
        src/sys/miscfs/procfs: procfs_linux.c
        src/sys/sys: param.h proc.h sysctl.h

Log Message:
As discussed in tech-kern:

- make sysctl kern.expose_address tri-state:
        0: no access
        1: access to processes with open /dev/kmem
        2: access to everyone
  defaults:
        0: KASLR kernels
        1: non-KASLR kernels

- improve efficiency by calling get_expose_address() per sysctl, not per
  process.

- don't expose addresses for linux procfs

- welcome to 8.99.27, changes to fill_*proc ABI
