I did a compile test without the relaxed change. It built just fine.
CONFIG_64BIT is also not defined in the .config file from kbuild.
I also dropped this patch on v5 due to Steve's request.

However, I think I still need an answer for 
v6: RDMA/qedr: eliminate duplicate barriers on weakly-ordered archs #2
I can switch to #include <linux/io-64-nonatomic-lo-hi.h> there.
