Linus,

please pull the latest printk changes from

git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk tags/printk-for-4.19

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

- Different vendors have a different expectation about a console quietness.
Make it configurable to reduce bike-shedding about the upstream default.

- Decide about the message visibility when the message is stored. It avoids
races caused by a delayed console handling.

- Always store printk() messages into the per-CPU buffers again in NMI.
The only exception is when flushing trace log in panic(). There
the risk of loosing messages is worth an eventual reordering.

- Handle invalid %pO printf modifiers correctly.

- Better handle %p printf modifier tests before crng is initialized.

- Some clean up.
