I misread what you meant with the word "from".

But my point is still that this is not a regression in the kernel but a 
problem when using gcc 4.2 on powerpc (no matter whether the kernel or 
gcc is wrong in this case).

Or am I wrong here and you are able to compile older powerpc kernels 
with the same gcc and .config?
