From ab799dede9b6d744a926dcb657ed5b30f401f151 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Tue, 16 Oct 2007 23:26:54 -0700 Subject: [PATCH] Add linux/elfcore-compat.h 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. It's a clean-up that every arch with compat core dumping code can benefit from. I only touched the ones I have handy to test at home. Doing the same for each other arch should be straightforward, and I'm happy to offer tips.
