Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk
Pull printk updates from Petr Mladek: - There is a situation when early console is not deregistered because the preferred one matches a wrong entry. It caused messages to appear twice. This is the 2nd attempt to fix it. The first one was wrong, see the commit c6c7d83b9c9e ('Revert "console: don't prefer first registered if DT specifies stdout-path"'). The fix is coupled with some small code clean up. Well, the console registration code would deserve a big one. We need to think about it. - Do not lose information about the preemtive context when the console semaphore is re-taken. - Do not block CPU hotplug when someone else is already pushing messages to the console. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk: printk: fix double printing with earlycon printk: rename selected_console -> preferred_console printk: fix name/type/scope of preferred_console var printk: Correctly handle preemption in console_unlock() printk: use console_trylock() in console_cpu_notify()
