    Subject[PATCH-linux-next] ia64: fix build breakage in smp.h
    The commit:
    "cpumask: switch over to cpu_online/possible/active/present_mask"
    provides a define for cpu_online_map but did not delete the
    declaration in arch/ia64/include/asm/smp.h resulting in this
    build error:

    CC arch/ia64/kernel/asm-offsets.s
    In file included from include/linux/smp.h:30,
    from include/linux/sched.h:68,
    from arch/ia64/kernel/asm-offsets.c:9:
    arch/ia64/include/asm/smp.h:60: error: expected ')' before '*' token
    arch/ia64/include/asm/smp.h:60: error: expected ')' before 'cpu_online_mask'

    Fix: just delete the declaration, it is no longer needed.

    Ingo: I think this belongs in the auto-cpus4096-next branch of the tip tree
