Derzeit haben fast alle Linux-Distributionen, die weiterhin 32-Bit x86-Systeme unterst\u00fctzen, auf den Kernel-Build mit der Option X86_PAE umgestellt, die die Unterst\u00fctzung von \u201ecmpxchg8b\u201c erfordert.      <\/p>\n<p>Laut Linus haben i486-Prozessoren aus Sicht der Kernel-Unterst\u00fctzung ihre Relevanz verloren, auch wenn sie immer noch verbreitet sind.
