What I need is a clear indication that the fix contains platform
specific code and therefor have to be ported (or validated) to other
platforms like AArch64.
Label seems to me the most natural way to provide such indication, but
any other approach will work for me as soon as I can easy select all
changes for period that requires my attention.
