While I was commiting this to ath-next-test for build tests and review,
I had a trivial conflict. Please check the patch:

https://github.com/kvalo/ath/commit/85dec746d1f4728176bd06a53b6da4ef014f2a27

Oddly enough with this patch I see a new warning:

include/uapi/linux/swab.h:71:16: error: undefined identifier '__builtin_bswap64'

But I guess there's not much we can do about that?
