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 * tag 'printk-for-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: printk: nbcon: Allow reacquire during panic printk: Allow to use the printk kthread immediately even for 1st nbcon slab: Decouple slab_debug and no_hash_pointers vsprintf: Use __diag macros to disable '-Wsuggest-attribute=format' compiler-gcc.h: Introduce __diag_GCC_all
