Which I can confirm:
this works:
git checkout 47da421981571c69ef29740cc55fa7248682e167
save this version of arch/powerpc/sysdev/ppc4xx_msi.c
this reboots:
git checkout 247540b03bfcbbe26b86692c9424195d76eb67f0
fix .config
CONFIG_PPC_DISABLE_WERROR=y
#CONDIF_PPC_WERROR is not used
cp ../ppc4xx_msi.c from 47da421981571c69ef29740cc55fa7248682e167 to
arch/powerpc/sysdev/ppc4xx_msi.c and voila this works.
