Hi Alex,

This is part of our effort to isolate FPU code inside DML (right now, we 
are only missing DCN30); since we are really close to that, many of 
these guards become useless. All of these patches were tested in our CI 
against:

1. x86 with DCN
2. x86 without DCN
3. Clang
4. make allmodconfig

Additionally, I think that Alex Hung also checked the compilation with 
PowerPC.

Thanks
Siqueira
