No, GFP_DMA is a NOP on PPC.
Actually the problems seems much more complex and a correct fix
seems to be hard to do.
I think benh is actually fixing this.

To summerize: I actually added these messages, because people were
hitting "this does not work with >1G" issues and did not get an error message.
So I decided to insert warnings until the issue is fixed inside the arch code.
I will remove them once the issue is fixed.

Greetings Michael.
