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
* tag 'printk-for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk:
lib/vsprintf: Do not handle %pO[^F] as %px
printk: Fix warning about unused suppress_message_printing
printk/nmi: Prevent deadlock when accessing the main log buffer in NMI
printk: Create helper function to queue deferred console handling
printk: Split the code for storing a message into the log buffer
printk: Clean up syslog_print_all()
printk: Remove unnecessary kmalloc() from syslog during clear
printk: Make CONSOLE_LOGLEVEL_QUIET configurable
printk: make sure to print log on console.
lib/test_printf.c: accept "ptrval" as valid result for plain 'p' tests
