New Revision: 214004
URL: http://svn.freebsd.org/changeset/base/214004

Log:
  Rename boot() to kern_reboot() and make it visible outside of
  kern_shutdown.c. This makes it easier for emulators and other
  parts of the kernel to initiate a reboot.

Modified:
  head/sys/kern/kern_shutdown.c
  head/sys/sys/systm.h
