[parisc-linux] Fix for uninitialised variable in new seq_file code for arch/parisc/ikernel/rq.c

[James Bottomley]

The compiler justly complains in this:

        unsigned int regnr = *(loff_t *) v, i;

        if (regnr == 0) {
                seq_puts(p, "     ");
#ifdef CONFIG_SMP
                for (i = 0; i < NR_CPUS; i++)
#endif
                        seq_printf(p, "      CPU%02d ", i);


That i is uninitialised if CONFIG_SMP is not set.
