Pull printk updates from Petr Mladek:

 - Add new "hash_pointers=[auto|always|never]" boot parameter to force
   the hashing even with "slab_debug" enabled

 - Allow to stop CPU, after losing nbcon console ownership during
   panic(), even without proper NMI

 - Allow to use the printk kthread immediately even for the 1st
   registered nbcon

 - Compiler warning removal
