I think you are better off disabling CONFIGURABLE_MEMORY_LAYOUT for ppc and doing the memory layout completely on your own. You will have more freedom selecting suitable base/sizes for stack and malloc area. > diff --git a/include/asm-generic/memory_layout.h b/include/asm-generic/memory_layout.h > index 45e0ed8..7a23db1 100644 > --- a/include/asm-generic/memory_layout.h > +++ b/include/asm-generic/memory_layout.h > @@ -2,9 +2,13 @@ > #define __ASM_GENERIC_MEMORY_LAYOUT_H > > #ifdef CONFIG_MEMORY_LAYOUT_DEFAULT > +#ifdef CONFIG_PPC > +#define STACK_BASE ((unsigned long)&_stext - CONFIG_STACK_SIZE) > +#else Plus I don't really want to broaden the use of STACK_BASE, even less when you have to special case it for PPC.
