Thanks for the information.

I am not seeing this issue or even a warning when using the ARM 8.3 
toolchain even in a clean build.

arm-linux-gnueabihf-gcc (GNU Toolchain for the A-profile Architecture 
8.3-2019.03 (arm-rel-8.36)) 8.3.0

So is a bug in this toolchain?

I did Google the issue and got the answer I guess I just question to why 
I am not seeing the error because for me the patchset builds fine no errors.

And why is this only reported on the MIPS arch.  Not saying that it is 
not an issue in the code just wondering how it gets there.

I will try to reproduce the error and then apply the changes.
