[Sorry for the "timely" response.]
Although the mechanisms for managing and identifying an alternative JVM are not platform-specific, the mitigation strategy proposed (e.g. the specific gcc options) are x86-specific.
I suggest adding a note in the JEP that the specific mitigations proposed are x86 specific, and that other ports will need to identify what mitigations are appropriate (if any).
I'll start up a discussion in the aarch64 list on what we should do about limiting speculative execution, and we may link aarch64-specific enhancements to this JEP. This needs to be looked at for both C++ options and JIT implementation on aarch64.
