I see some %p-s being used in _supposedly_ important output,
like arch/x86/mm/fault.c

show_fault_oops(struct pt_regs *regs, unsigned long error_code,
                unsigned long address)
...
        printk(KERN_CONT " at %p\n", (void *) address);
        printk(KERN_ALERT "IP: %pS\n", (void *)regs->ip);

So %pS isn't %p, and shows the symbolic name.

If the symbolic name is available.
Else it prints the non-hashed pointer value (FTR).
