Subject: [PATCH] x86,edac: fix for compiler error in traps.c

Impact: compile fix

 I got this compile failure on both tip/tracing/core as well as on 
 v2.6.30-rc1.

   LD      .tmp_vmlinux1
 arch/x86/kernel/built-in.o: In function `do_nmi':
 (.text+0x3c18): undefined reference to `edac_handler_set'
 arch/x86/kernel/built-in.o: In function `do_nmi':
 (.text+0x3c48): undefined reference to `edac_atomic_assert_error'
 make: *** [.tmp_vmlinux1] Error 1
 [root@...hel51 linux-trace.git]# grep edac_handler_set 
 [root@...hel51 linux-trace.git]# Grep edac_handler_set '*.[ch]'
 find .  -name "*.[ch]" ! -type d  | xargs grep  "edac_handler_set"
 ./arch/x86/kernel/traps.c:	if (edac_handler_set()) {
 ./include/linux/edac.h:extern int edac_handler_set(void);
 ./drivers/edac/edac_stub.c:int edac_handler_set(void)
 ./drivers/edac/edac_stub.c:EXPORT_SYMBOL_GPL(edac_handler_set);

This patch seems to fix it.
