While debugging the kdump kernel, I found there is a compiling error: If is_kdump_kernel() is called in some driver(for example, add it in debugging code in module qla2xxx), there will be a compiling error:
ERROR: "elfcorehdr_addr" [drivers/scsi/qla2xxx/qla2xxx.ko] undefined! Add EXPORT_SYMBOL for elfcorehdr_addr will fix this.
