The Linux kernel doesn't use it in any 32-bit configuration: https://git.kernel.org/linus/ba0593bf553c450a03dbc5f8c1f0ff58b778a0c8 gas was also changed to not generate long-NOPs when the target is the generic 'i686' rather than a specific core: https://sourceware.org/ml/binutils-cvs/2010-08/msg00057.html So the Geode processors should remain supported.
