  12  * benedict.gaster@superh.com:   2nd May 2002
  13  *    Add definition of empty_zero_page to be the first page of kernel image.
  14  *
  15  * benedict.gaster@superh.com:   3rd May 2002
  16  *    Added support for ramdisk, removing statically linked romfs at the same time.
  17  *
  18  * lethal@linux-sh.org:          9th May 2003
  19  *    Kill off GLOBAL_NAME() usage and other CDC-isms.
  20  *
  21  * lethal@linux-sh.org:         19th May 2003
  22  *    Remove support for ancient toolchains.
