[merged] ia64-mca-always-make-ia64_mca_debug-an-expression.patch removed from -mm tree

[akpm@linux-foundation.org]

The patch titled
     Subject: ia64: mca: always make IA64_MCA_DEBUG an expression
has been removed from the -mm tree.  Its filename was
     ia64-mca-always-make-ia64_mca_debug-an-expression.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Sergei Trofimovich <slyfox@gentoo.org>
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.
