Merge tag 'printk-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk
Pull printk updates from Petr Mladek:
- Fix two more locations where printf formatting leaked pointers
- Better log_buf_len parameter handling
- Add prefix to messages from printk code
- Do not miss messages on other consoles when the log is replayed on a
new one
- Reduce race between console registration and panic() when the log
might get replayed on all consoles
- Some cont buffer code clean up
- Call console only when there is something to do (log vs cont buffer)
