Subject: consolidate oops end/ID printing code in panic.c
From: Arjan van de Ven <arjan@...ux.intel.com>
CC: Ingo Molnar <mingo@...e.hu>
CC: Andrew Morton <akpm@...ux-foundation.org>

This patch consolidates the 2 places that print an oops end marker and ID
into a single function; this patch follows the WARN_ON uninline and the
WARN_ON enhancement patches.
