Hi Ao,

First of all, thanks a lot for this patch.

Move remaining FPU code to dml folder
in preparation for enabling aarch64 support.

I guess you found some of the issues here after you tried enabling the arm64 compilation, right? If so, could you expand the commit message to describe it better?

Could you split this commit in two parts?
One for DCN10 and another one for DCN32.

Since this is a small function signature, could you add the dc parameter in the same line as the function name? Same idea for the header file.

Drop the extra space in the above line.
