Subject: [GIT PULL] printk for 4.20

Linus,

please pull the latest printk changes from

  git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk tags/printk-for-4.20

==================

- 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).
