Actually I think is controls %pK.

The code here is what I was referring to.

		/*
		 * kptr_restrict==1 cannot be used in IRQ context
		 * because its test for CAP_SYSLOG would be meaningless.
		 */
		if (in_irq() || in_serving_softirq() || in_nmi()) {
			if (spec.field_width == -1)
				spec.field_width = 2 * sizeof(ptr);
			return error_string(buf, end, "pK-error", spec);
		}
