olh is an 'extern int' and referenced in
arch/ppc/platforms/pmac_pci.c:pmac_pcibios_fixup()


extern int olh;
void __init
pmac_pcibios_fixup(void)
{
        /* Fixup interrupts according to OF tree */
        pcibios_fixup_OF_interrupts();
        olh = 1;
}


how to reproduce:
tar xfj linux-2.6.7.tar.bz2
cd linux-2.6.7
bzip2 -cd ../patch-2.6.8-rc4.bz | patch -Esp1
.. make the change above ...
cp arch/ppc/defconfig .config
yes '' | make ARCH=ppc -j4 oldconfig
make ARCH=ppc -j4 vmlinux
