Subject: [PATCH] ia64: mca: always make IA64_MCA_DEBUG an expression

At least ia64_mca_log_sal_error_record() expects some statement:

    static void ia64_mca_log_sal_error_record(int sal_info_type)
    {
        ...
        if (irq_safe)
            IA64_MCA_DEBUG("CPU %d: SAL log contains %s error record\n",
                smp_processor_id(),
                sal_info_type < ARRAY_SIZE(rec_name) ? rec_name[sal_info_type] : "UNKNOWN");
        ...
    }

Instead of fixing all callers the change expicitly makes IA64_MCA_DEBUG
a non-empty expression.
