The first part can be found here[1]. The proposed changes do not
change the functionality of printk, but were suggestions made by
Petr Mladek. I already have more patches for a part 3 ,but I would like
to see these ones merged first.

I did the testing with VMs, checking suspend and resume cycles, and it worked
as expected.

Thanks for reviewing!
