Subject: 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
",
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.
