  • The patch series today though would end support for original i486 processors as well as early i586 processors. The kernel patches would remove support for CPUs lacking TSC and CX8/CMPXCHG8B capabilities. Basically this would put the minimum upstream Linux kernel support for 32-bit processors at the original Pentium CPU with CMPXCHG8B and Time Stamp Counter (TSC) support.

    There were 586 CPUs that were not Pentiums? Article implies the original Pentium would be the new baseline, but then what 586 CPUs would lose support?
