    Add __percpu sparse annotations to net.
    
    These annotations are to make sparse consider percpu variables to be
    in a different address space and warn if accessed without going
    through percpu accessors.  This patch doesn't affect normal builds.
    
    The macro and type tricks around snmp stats make things a bit
    interesting.  DEFINE/DECLARE_SNMP_STAT() macros mark the target field
    as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly.  All
    snmp_mib_*() users which used to cast the argument to (void **) are
    updated to cast it to (void __percpu **).
