Interesting …

Yes, of course. - Does the double negation in this wording indicate another
special software development concern?

How do you think about another update suggestion like "[PATCH] MD-RAID: Use seq_putc()
in three status functions" (from 2016-10-16)?
https://patchwork.kernel.org/patch/9378055/
https://lkml.kernel.org/r/<77fb6fdc-7480-8607-0af1-42f73c125b9d@users.sourceforge.net>

I am curious what your opinions will be for further development of the
function "show_cpuinfo" in the source file "arch/arc/kernel/setup.c".
