Linus,
please pull the latest printk changes from
git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk.git for-linus
==========
- 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 2nd attempt to fix it. The first one was wrong,
see the commit c6c7d83b9c9e6a8b3e6 ('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.
