Arutledes x86-protsessoritega, mis ei toeta k\u00e4sku «cmpxchg8b», m\u00e4rkis Linus Torvalds, et v\u00f5ib-olla on aeg kuulutada selle k\u00e4su olemasolu tuuma t\u00f6\u00f6ks kohustuslikuks ja loobuda i486-protsessorite toetamist, mis ei toeta «cmpxchg8b», selle asemel et proovida seda k\u00e4su emuleerimist protsessoritel, mida enam keegi ei kasuta. Praegu on peaaegu k\u00f5ik Linuxi jaotused, mis j\u00e4tkavad 32-bitiste x86-s\u00fcsteemide toetust, \u00fcleminekuks tuuma versioonile X86_PAE, mis n\u00f5uab «cmpxchg8b» toetust. <\/p>\n

Linuse arvates on i486-protsessorid tuuma toetuse seisukohalt kaotanud oma t\u00e4htsuse, kuigi need on endiselt olemas. Teatud hetkel muutuvad protsessorid muuseumieksponaatideks ja nende jaoks saab kasutada «muuseumide» tuumasid. Kasutajad, kellel on endiselt i486-protsessoritega s\u00fcsteeme, saavad kasutada LTS-v\u00e4ljaandeid, mille tuuma toetus kestab veel palju aastaid. <\/p>\n

Klassikaliste i486 protsessorite toe l\u00f5petamine ei m\u00f5juta Intel'i toodetud Quark sisseehitatud protsessoreid, mis kuigi kuuluvad i486 klassi, sisaldavad Pentiumi p\u00f5lvkonnale iseloomulikke lisainstruktsioone, sealhulgas «cmpxchg8b». Sama kehtib ka Vortex86DX protsessorite kohta. i386 protsessorite toe l\u00f5petamine toimus tuumas 10 aastat tagasi.
