In addition, the big change coming will specifically affect system calls, which is why it will have a bigger effect on servers and applications which use system resources (time, file information, and much more). Games tend to be light on system calls, which is why they aren't affected as heavily by the fix for meltdown.
As for FRC, the RoboRio uses an ARM processor, which means that it will not require a fix for meltdown.
Note: there is no immediate fix I am aware of coming for spectre, although all processors are susceptible afaik.
