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
