Merge tag 'printk-for-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- New "no_hash_pointers" kernel parameter causes that %p shows raw
pointer values instead of hashed ones. It is intended only for
debugging purposes. Misuse is prevented by a fat warning message that
is inspired by trace_printk().
- Prevent a possible deadlock when flushing printk_safe buffers during
panic().
- Fix performance regression caused by the lockless printk ringbuffer.
It was visible with huge log buffer and long messages.
- Documentation fix-up.
