From f408b43ceedce49f26c01cd4a68dbbdbe2743e51 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Tue, 1 Apr 2008 15:44:01 -0700 Subject: [PATCH] x86: fix VisualWS and Voyager kexec build failures without this patch: VOYAGER: kernel/built-in.o: In function `crash_kexec': (.text+0x28588): undefined reference to `machine_crash_shutdown' VISWS: kernel/built-in.o: In function `crash_kexec': /next-20080401/kernel/kexec.c:1074: undefined reference to `machine_crash_shutdown' make[1]: *** [.tmp_vmlinux1] Error 1 because arch/x86/kernel/reboot.c isn't built since CONFIG_X86_BIOS_REBOOT=n, so machine_crash_shutdown() isn't available. This patch does seem a small bit odd since the KEXEC help text says that kexec is independent of the system firmware.
