That's in fixes. I'll sort it out when I apply this, or when I merge fixes into next. > I can't see any R_PPC_UADDR32 relocations generated by ppc4xx_defconfig > + CONFIG_RELOCATABLE unless I revert that commit. Presumably this change accidentally aligns the syscall table. >> After this patch, 44x_defconfig + CONFIG_RELOCATABLE boots to busybox. So that's probably just because of the alignment too. I think this patch should go after .data.rel.ro is made read only. cheers
