I think we should reconsider these two commits, then.

The use of the PRIx?? macros is really ugly and makes the code very
hard to read.  This alone should be reason to avoid that - in addition
we deviate from the Linux kernel, so adapting code from there becomes
much more difficult.

I think we should especially strive to maintain compatibility with
Linux code.

Best regards,
