Facilitate using crash_save_cpu() on ia64 by adding kdump_elf_core_copy_regs(). By default kdump_elf_core_copy_regs() is just defined to be elf_core_copy_regs(), which is what crash_save_cpu() previously used. ia64 (and other architectures) are able to define their own implementations as needed. Signed-off-by: Simon Horman <horms@xxxxxxxxxxxx> --- * This patch applies on top of the note size calculation patch that can be found in mm and at http://lists.linux-foundation.org/pipermail/fastboot/2007-April/006792.html Porting this patch to not require that one is quite trivial. I can supply a port or a thread containing both patches if it helps. linux-2.6/include/linux/kexec.h | 5 +++++ linux-2.6/kernel/kexec.c | 2 +- 2 files changed, 6 insertions(+), 1 deletion(-) Index: linux-2.6/include/linux/kexec.h =================================================================== --- linux-2.6.orig/include/linux/kexec.h 2007-05-08 17:49:35.000000000 +0900 +++ linux-2.6/include/linux/kexec.h 2007-05-08 17:49:51.000000000 +0900 @@ -128,6 +128,11 @@ extern struct kimage *kexec_crash_image; #define kexec_flush_icache_page(page) #endif +#ifndef kexec_elf_core_copy_regs +#define kexec_elf_core_copy_regs(elfregs, regs) \ + elf_core_copy_regs(elfregs, regs) +#endif + #define KEXEC_ON_CRASH 0x00000001 #define KEXEC_ARCH_MASK 0xffff0000 Index: linux-2.6/kernel/kexec.c =================================================================== --- linux-2.6.orig/kernel/kexec.c 2007-05-08 17:49:35.000000000 +0900 +++ linux-2.6/kernel/kexec.c 2007-05-08 17:49:51.000000000 +0900 @@ -1117,7 +1117,7 @@ void crash_save_cpu(struct pt_regs *regs return; memset(&prstatus, 0, sizeof(prstatus)); prstatus.pr_pid = current->pid; - elf_core_copy_regs(&prstatus.pr_reg, regs); + kexec_elf_core_copy_regs(&prstatus.pr_reg, regs); buf = append_elf_note(buf, KEXEC_CORE_NOTE_NAME, NT_PRSTATUS, &prstatus, sizeof(prstatus)); final_note(buf); -- -- Horms H: http://www.vergenet.net/~horms/ W: http://www.valinux.co.jp/en/ - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
