This replaces Version 1 of this patch, which broke the build when CONFIG_KEXEC and CONFIG_CRASH_DUMP were configured off. In that case the storage for the 'in_crash_kexec' flag was never built. This version defines that flag as 0 if CONFIG_KEXEC is not set. The patch is tested with all combinations of those two options.
