[PATCH 16/22] UML - S390 preparation, elf.h
From: Jeff Dike
Date: Sun May 01 2005 - 17:12:36 EST
From: Bodo Stroesser <bstroesser@xxxxxxxxxxxxxxxxxxx>
This patch make elh.h a symlink to the new arch-specific
include files of the form elf-<subarch>.h, as in the same
way already is done for some other includes.
Also moves Elf-stuff from archparam-<subarch>.h and
elf.h to the new elf-<subarch>.h files.
