Indeed, thanks for the note! Will add this in my v3.
For ARC I'd like this fix to be back-ported starting from v4.8 where we added support of "native" atomic64_t, see commit ce6365270ecd (" ARCv2: Implement atomic64 based on LLOCKD/SCONDD instructions").
What about m68k, do you have any preference of earliest kernel version where this fix might be useful?
