we're trying to compile a kernel for an embedded system with a 
MIPS64-processor on it.
We tried first with your CVS-sources, but there we get this error:

  Generating include/linux/version.h (unchanged)
make[1]: Nothing to be done for `__build'.
  SPLIT  include/linux/autoconf.h -> include/config/*
make -f scripts/ obj=arch/mips64/kernel 
make[1]: `arch/mips64/kernel/offset.s' is up to date.
/bin/sh: arch/mips64/kernel/offset.s: Datei oder Verzeichnis nicht gefunden

Afterwards we changed to the 2.4.20 stock kernel, there we have managed to get 
the kernel compiling the first steps. We're using the algor SDE-Toolchain and 
on make vmlinux, we get masses of parse-errors.
Our point of view is, that the compiler tries to link to include/asm instead 
of include/asm-mips64, but doing a dirty simlink from asm to asm-mips64 
didn't really improve our situation.
Here are some of the errors we get:

-Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer
