Message-Id: <20070803232121.A252E4D04BC@magilla.localdomain> Date: Fri, 3 Aug 2007 16:21:21 -0700 (PDT) Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2385 Lines: 81 This adds the linux/elfcore-compat.h header file, which is the CONFIG_COMPAT analog of the linux/elfcore.h header. Each arch that needs to fake out fs/binfmt_elf.c for its compat code can use this header to replace the hand-copied definitions of the compat variants of struct elf_prstatus et al. Only the pr_reg field varies by arch, so asm/{compat,elf}.h must define compat_elf_gregset_t before linux/elfcore-compat.h can be used.
