I don't understand the intent of breaking the existing arch's first at all. Just leave them alone. When the arch hook is not defined, just 0-fill the siginfo_t. If you do the patches in the right order, then there will never even be a tree state where powerpc et al get any change at all before the final one. Thanks, Roland
