I moved it quite simply because I keep entries in order:

        unsigned                l2c_aux_val;    /* L2 cache aux value   */
        unsigned                l2c_aux_mask;   /* L2 cache aux mask    */
        void                    (*l2c_write_sec)(unsigned long, unsigned);
        struct smp_operations   *smp;           /* SMP operations       */
        bool                    (*smp_init)(void);
        void                    (*fixup)(struct tag *, char **,
                                         struct meminfo *);
        void                    (*init_meminfo)(void);
        void                    (*reserve)(void);/* reserve mem blocks  */
        void                    (*map_io)(void);/* IO mapping function  */
        void                    (*init_early)(void);

And the order of declaration in there (for the functions after "smp")
is the order in which they are called during kernel initialisation.
Platforms randomising their declarations is... silly.  And yes, I'll
move those l2c ones before .smp.
