    commit 8f0ea0fe (snmp: reduce percpu needs by 50%)
    reduced snmp array size to 1, so technically it doesn't have to be
    an array any more. What's more, after the following commit:
    	commit 933393f5
    	Date:   Thu Dec 22 11:58:51 2011 -0600
    	    percpu: Remove irqsafe_cpu_xxx variants
    	    We simply say that regular this_cpu use must be safe regardless of
    	    preemption and interrupt state.  That has no material change for x86
    	    and s390 implementations of this_cpu operations.  However, arches that
    	    do not provide their own implementation for this_cpu operations will
    	    now get code generated that disables interrupts instead of preemption.
    probably no arch wants to have SNMP_ARRAY_SZ == 2. At least after
    almost 3 years, no one complains.
    So, just convert the array to a single pointer and remove snmp_mib_init()
    and snmp_mib_free() as well.
