Merge tag 'printk-for-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/printk...

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

                        slab_debug can create guard zones around objects and
                        may poison objects when not in use. Also tracks the
                        last alloc / free. For more information see

+                       Using this option implies the "no_hash_pointers"
+                       option which can be undone by adding the
+                       "hash_pointers=always" option.

        slab_max_order= [MM]
                        Determines the maximum allowed order for slabs.
                        A high setting may cause OOMs due to memory
