Please see the other 2 threads on the list. There is a fix under way for
Clang, so I don't think there is a need for this hack.

If you're using Clang to compile the kernel, you're already carrying a
number of extra patches, so adding this one shouldn't be a big deal.
Once Clang gains feature parity with GCC, you'll be able to drop it.

Thanks,
