Arm Changing Linux Default To Costly "KPTI" Mitigation For Some Newer CPUs

For some newer Arm core designs, Arm is changing the Linux kernel to defaulting to enabling Kernel Page Table Isolation "KPTI" if not running on a new firmware version in order to properly mitigate a recently disclosed CPU security issue. This change has been queued up and is expected to change the default with the upcoming Linux 6.15 kernel.

Many still have nightmares around Page Table Isolation mitigation costs from the Meltdown period... Unfortunately, it's turned out to be needed for some newer Arm core designs if not having a new firmware in place with an alternative mitigation strategy.

Back in January, #Arm made public CVE-2024-7881. They described of CVE-2024-7881 in their disclosure:
