Agreed.

For consistency, it does make sense to have the common x86 and ARM64
code outputing information in the same way, so I think the patch still
makes sense. All of them could be moved to KERN_DEBUG as a separate
patch if we want to cull early boot output. I would split that off and
discuss it separately.
