Patches for the Linux kernel are pending for implementing this Intel AEX Notify support with capable processors.
Indirect Branch Tracking (IBT) is still being eyed for enabling as part of the default Linux x86_64 kernel configurations to provide better out-of-the-box security on supported processors. A patch sent out today continues the upstream discussion over flipping on this feature by default that is part of Intel's Control-flow Enforcement Technology (CET) for helping to defend against jump/call oriented programming attacks.
