The paper from the other people who discovered this says the same thing: "We also tried to reproduce the Meltdown bug on several ARM and AMD CPUs. However, we did not manage
to successfully leak kernel memory with the attack de-
scribed in Section 5, neither on ARM nor on AMD." The general purpose attack that leaks kernel memory, the one that KAISER fixes, only seems to work on Intel CPUs. Intel's press release was misleading.

It would be interesting to see details e.g. on how the branch prediction of other modern processors works and how well it can be attacked." So it seems like they tried it on AMD and ARM, but they tried much harder on Intel. That's less reassuring than my initial reading.
