[PATCH] powerpc/traps: fix the message printed when stack overflows

[Christophe Leroy]

Today's message is useless:

[   42.253267] Kernel stack overflow in process (ptrval), r1=c65500b0

This patch fixes it:

[   66.905235] Kernel stack overflow in process sh[356], r1=c65560b0

Fixes: ad67b74d2469 ("printk: hash addresses printed with %p")
