\u00cen cadrul discu\u021biei despre metodele alternative de operare pe procesoarele x86 care nu suport\u0103 instruc\u021biunea «cmpxchg8b», Linus Torvalds a declarat c\u0103 poate a sosit momentul s\u0103 declar\u0103m aceast\u0103 instruc\u021biune drept obligatorie pentru func\u021bionarea nucleului \u0219i s\u0103 renun\u021b\u0103m la suportul pentru procesoarele i486, care nu pot utiliza «cmpxchg8b», \u00een loc s\u0103 \u00eencerc\u0103m s\u0103 emul\u0103m func\u021bionarea acestei instruc\u021biuni pe procesoare pe care nimeni nu le folose\u0219te deja. \u00cen prezent, aproape toate distribu\u021biile Linux care continu\u0103 s\u0103 sus\u021bin\u0103 sistemele x86 pe 32 de bi\u021bi au trecut la compilarea nucleului cu op\u021biunea X86_PAE, care necesit\u0103 suport pentru «cmpxchg8b». <\/p>\n

Din opinia lui Linus, din perspectiva sus\u021binerii \u00een nucleu, procesoarele i486 au pierdut relevan\u021ba, chiar dac\u0103 ele sunt \u00eenc\u0103 \u00eent\u00e2lnite \u00een utilizare. La un anumit moment, procesoarele devin exponate de muzeu \u0219i pentru ele se poate recurge la nuclee «de muzeu». Utilizatorii care mai au sisteme cu procesoare i486 vor putea utiliza versiuni LTS ale nucleului, care vor fi sus\u021binute \u00eenc\u0103 mul\u021bi ani. <\/p>\n

\u00cencetarea suportului pentru clasicele i486 nu va afecta procesoarele integrate Quark produse de Intel, care, de\u0219i se \u00eencadreaz\u0103 \u00een clasa i486, includ instruc\u021biuni suplimentare specifice genera\u021biei Pentium, inclusiv «cmpxchg8b». Aceea\u0219i situa\u021bie se aplic\u0103 \u0219i procesoarelor Vortex86DX. Suportul pentru procesoarele i386 a fost oprit \u00een nucleu acum 10 ani.
