[PATCH] parisc /proc/interrupts uninitialised var

From: James Bottomley <James.Bottomley@SteelEye.com>

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.
