gee.  There are a lot of callers of emergency_restart().  Why is the
BMC reboot special, and how many of the emergency_restart() callers
really be using orderly_reboot()?

We have /proc/sys/kernel/poweroff_cmd.  Should we have
/proc/sys/kernel/reboot_cmd as well?  If not,
kernel/reboot.c:reboot_cmd[] can be made static ;)
