Can't compile 2.4 on PReP w/ potato

[Frank Weis <Frank.Weis@astron.lu>]

Hi all,

i want to compile 2.4 on my PReP (Motorola Powerstack) in order to get 
framebuffer support for the builtin CLGD-5434 so that I can run X.

First there is an error in the headers: <asm/mmu.h> contains a typedef that 
isn't enclosed in #ifndef __ASSEMBLY__

After having corrected that, the make runs fine until the final link, 
where I get an undefined 
get_cpuinfo

I have grepped around the sources and found a definition of this function 
only in connection with SMP.

Ok, I configured support for SMP back on, make clean; make dep; make zImage

and compilation fais again at the linking phase. Here is the beginnning of 
the error message:

I use a stock 2.2r2.

Any hints?
