New Revision: 250814
URL: http://svnweb.freebsd.org/changeset/base/250814

Log:
  Being exported through vdso the note.Linux section used by glibc
  to determine the kernel version (this saves one uname call).
  Temporarily disable the export of a note.Linux section until I figured
  out how to change the kernel version in the note.Linux on the fly.
