No change needed there - it was correct in arch/ppc, just not in arch/ 
powerpc.  The 8540 patch was based on a slightly older copy of the  
file that didn't have this change and we didn't catch the problem in  
testing because the FPU isn't enabled for 8540.  I discovered this  

The 8540 flat tree support patch added this file to arch/powerpc/ 
kernel.  As you pointed out in a different mail, this patch has  
disappeared from the tree recently.
