Hm, so the umbrella term is CPU_MITIGATIONS, the x86-one is
SPECULATION_MITIGATIONS.
I wanna streamline our namespacing and say, the arch agnostic term
should be CPU_MITIGATIONS and the x86 one should be then
X86_CPU_MITIGATIONS, the Arm one would be ARM_CPU_MITIGATIONS and so on.
This way we can stick all kinds of special mitigations code - not only
speculative execution ones - under those config items and have it all
straight from the get-go.
And I think we should do it now, before it all propagates down the tree
and becomes a lot harder to rename.
Thoughts?
Thx.
