Module Name:    src
Committed By:   dyoung
Date:           Wed Mar  5 07:09:18 UTC 2008

Modified Files:
        src/sys/kern: kern_drvctl.c kern_pmf.c subr_autoconf.c
        src/sys/sys: device.h

Log Message:
Synchronize readers and writers of the device tree.

Add a device iterator object, deviter_t, and methods deviter_init(),
deviter_first(), and deviter_next() for visiting each device in
the device tree.

Take care not to re-shutdown a device in the event that the machine
panics during reboot and the operator types 'reboot' at the kernel
debugger prompt.

While I'm here, sprinkle PMF_FN_ARGS, PMF_FN_PROTO, et cetera.
