Yep, all very good advices. And while following the above, you will hopefully
notice things that need bug fixes, cleanups, or other work.

E.g. one thing I just noticed: while include/linux/compiler-gcc.h provides
shorthands (e.g. "__printf()") for various gcc __attribute__ macros, there
are still many places that don't use the shorthands, cfr. e.g.
"git grep 'attribute.*printf'".

As some of these are in architecture-specific header files, and need build
testing there, this is an opportunity to get some cross-compilers going (you
can download binaries from https://www.kernel.org/pub/tools/crosstool/) as
well.

Good luck, thanks, and welcome to the team! ;-)
