 Understood. The situation here is that the boards, which required these
modifications, have no support in the arch/powerpc branch. So this is 
why we made this in arch/ppc.

Bit of a dilemma then.  What board exactly?

 These are the Katmai and Yucca PPC440SPe-based boards (from AMCC).

Hm...  We should get those in.  At this point in the kernel cycle, your
patch would be 2.6.25 material anyway so perhaps there is some time to
get Katmai and Yucca done by then.

Also, I'd rather see something along the lines of hugetlbfs support instead.

 Here I agree with Benjamin. Furthermore, IIRC the hugetlb file-system is
supported for PPC64 architectures only. Here we have PPC32.

Well that needs fixing anyway, but ok.  Also, is the modified binutils
only required for userspace to take advantage here?  Seems so, but I'd
just like to be sure.

 You are right, for userspace only. 

Ok.
