Merge tag 'printk-for-5.16-fixup' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk fixes from Petr Mladek:
- Try to flush backtraces from other CPUs also on the local one. This
was a regression caused by printk_safe buffers removal.
- Remove header dependency warning.
* tag 'printk-for-5.16-fixup' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux:
printk: Remove printk.h inclusion in percpu.h
