It's bogus. it's the other way around, it's needed and gcc trapped a kernel bug. If the contents of memory not declared volatile changes under GCC (like it can happen right now for xtime since it's declared non volatile), gcc has the full rights to crash the kernel at runtime. I know there are other bugs like this one in the kernel, but this is not a good reason to fix the known ones IMHO.
