Hello,
This patch will be dropped in V2 since another series already made these u64.
See a9d887dc1c60ed67f2271d66560cdcf864c4a578 in linux-next.
I have not tested compiling that commit in linux-next on 32 bit arch
but if it fails i can replace this commit with fix for that.

Also  I'm not the author of this commit.
Konrad Dybcio fast forwarded it to 5.8 from 4.14.
Fenglin Wu is the author and also created that commit message.

Thank you.

Best regards
Martin
