Not all consoles are created equal: depending on the actual hardware,

the UART to emit a message, which can cause application-level problems
when the kernel spews onto the console.

Any thoughts on this series? Happy to resend again, but if there are no
objections I'd love to see it merged sooner rather than later :)

Happy to resend too, just let me know.

There is no need to resend the patch. It is on my radar and I am
going to look at it.

Please, be patient, you hit conference, illness, after vacation
season. We do not want to unnecessarily delay it but it is
not a trivial change that might be accepted within minutes.

No worries, just wanted to make sure it hadn't been missed :)

Thanks,
Calvin
