svn commit: r293105 - head/sys/dev/rt

[Ian Lepore]

Author: ian

New Revision: 293105
URL: https://svnweb.freebsd.org/changeset/base/293105

Log:
  Eliminate code for walking through the early static env data.  This code
  is called from a device attach routine, and thus cannot be called before
  the cutover from static to dynamic kernel env.
