you already have that anyway! There are several kernel data structures that have padding in them ifdef'd on older gcc versions just to work around bugs; gcc2 -> gcc3 as a result has a major different abi anyway so I don't think your argument holds.. (and in 2.6, the gcc version is part of the VERMAGIC so the exact compiler is enforced anyway)
