Merge tag 'printk-for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk

Pull printk updates from Petr Mladek:

 - 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
