|
* Add definition of empty_zero_page to be the first page of kernel image.
|
|
*
|
|
* benedict.gaster@superh.com: 3rd May 2002
|
|
* Added support for ramdisk, removing statically linked romfs at the
|
|
* same time.

|
|
* lethal@linux-sh.org: 9th May 2003
|
|
* Kill off GLOBAL_NAME() usage and other CDC-isms.
|
|
*
|
|
* lethal@linux-sh.org: 19th May 2003
|
|
* Remove support for ancient toolchains.
