Scary.

If you're using an in order processor, a Nexus 9 tablet say, then you should be safe.

I wasn't thinking straight last night. Basically all in order application processors use speculative execution.

[blattimwind]

Even a low-power core like a Cortex-M7 can do some speculative execution through its branch predictor.

Though of course a M7 isn't running VMs, and probably isn't running any kind of attacker-controlled code (scripting included - its there, but rare), so many of the vectors aren't present.
