My aboriginal linux project builds tiny linux systems to run under  
qemu, producing as close to the same system as possible across a bunch  
of different architectures. The above change broke the mips r4k build  
I've been running under qemu.

Here's a toolchain and reproduction sequence:

   wget http://landley.net/aboriginal/bin/cross-compiler-mips.tar.bz2
   tar xvjf cross-compiler-mips.tar.bz2
   export PATH=$PWD/cross-compiler-mips/bin:$PATH
   make ARCH=mips allnoconfig KCONFIG_ALLCONFIG=miniconfig.mips
   make CROSS_COMPILE=mips- ARCH=mips

(The file miniconfig.mips is attached.)

It ends:

   CC      init/version.o
   LD      init/built-in.o
arch/mips/built-in.o: In function `local_r4k_flush_cache_page':
