From bf2083050d7879390ddedbd64e431cf167854a34 Mon Sep 17 00:00:00 2001 From: "akpm@osdl.org" Date: Mon, 9 Jan 2006 20:51:45 -0800 Subject: [PATCH] [PATCH] Kdump: powerpc and s390 build failure fix ) From: Vivek Goyal crash_setup_regs() is an architecture dependent function which is called in architecture independent section. So every architecture supporting kexec should at least provide a dummy definition of crash_setup_regs() even if crash dumping is not implemented yet, to avoid build failures.
