W trakcie dyskusji na temat obwod\u00f3w pracy na procesorach x86, kt\u00f3re nie obs\u0142uguj\u0105 instrukcji «cmpxchg8b», Linus Torvalds stwierdzi\u0142, \u017ce nadszed\u0142 czas, aby og\u0142osi\u0107 obowi\u0105zkowe wsparcie dla tej instrukcji w j\u0105drze i zrezygnowa\u0107 ze wsparcia dla procesor\u00f3w i486, kt\u00f3re nie obs\u0142uguj\u0105 «cmpxchg8b», zamiast pr\u00f3bowa\u0107 emulowa\u0107 dzia\u0142anie tej instrukcji na procesorach, kt\u00f3re ju\u017c nikt nie u\u017cywa. Obecnie prawie wszystkie dystrybucje Linux, kt\u00f3re wci\u0105\u017c wspieraj\u0105 32-bitowe systemy x86, przesz\u0142y na kompilacj\u0119 j\u0105dra z opcj\u0105 X86_PAE, kt\u00f3ra wymaga wsparcia dla «cmpxchg8b». <\/p>\n

Wed\u0142ug Linusa, w kontek\u015bcie wsparcia w j\u0105drze procesory i486 straci\u0142y na znaczeniu, mimo \u017ce wci\u0105\u017c s\u0105 w u\u017cyciu. W pewnym momencie procesory staj\u0105 si\u0119 eksponatami muzealnymi i mo\u017cna dla nich \u015bmia\u0142o korzysta\u0107 z «muzealnych» j\u0105der. U\u017cytkownicy, kt\u00f3rzy maj\u0105 systemy na procesorach i486, b\u0119d\u0105 mogli korzysta\u0107 z wyda\u0144 LTS j\u0105dra, kt\u00f3re b\u0119d\u0105 wspierane przez wiele lat. <\/p>\n

Zaprzestanie wsparcia dla klasycznych i486 nie wp\u0142ynie na wytwarzane przez firm\u0119 Intel wbudowane procesory Quark, kt\u00f3re, cho\u0107 nale\u017c\u0105 do klasy i486, zawieraj\u0105 dodatkowe instrukcje charakterystyczne dla generacji Pentium, w tym «cmpxchg8b». To samo dotyczy procesor\u00f3w Vortex86DX. Wsparcie dla procesor\u00f3w i386 zosta\u0142o zako\u0144czone w j\u0105drze 10 lat temu.
