CVS commit: src/sys/kern

Module Name:    src
Committed By:   riastradh
Date:           Mon Mar 20 00:30:03 UTC 2017

Modified Files:
        src/sys/kern: subr_autoconf.c

Log Message:
Make sure we hold alldevs_mtx for access to alldevs in deviter.

- Extend alldevs_mtx section in deviter_init.
- Assert ownership of alldevs_mtx in private functions:
  . deviter_reinit
  . deviter_next1
  . deviter_next2
- Acquire alldevs_mtx in deviter_next.

(alldevs_mtx is not relevant to the struct deviter object, which is
private to the caller who must guarantee exclusive access to it.)
