Both patches should go into mainline together with the lockless printk
ring buffer. It is already in linux-next via printk/linux.git,
branch printk-rework.

The plan is to get it into mainline when pr_cont() handling is solved.
It is more complicated than we hoped for, see

It is still not clear whether it will be ready for 5.10.

Andrew, would you mind when I take the three gdb/lockless-printk
related changes via printk tree to avoid synchronization problems?
