The train has already left the station on those. The other mitigations
don't have "MITIGAT*" at all in front of the name. I.e.:

config RETHUNK
config CALL_DEPTH_TRACKING
...

and prepending them all with MITIGATION_ is going to cause too much
senseless churn for a reason which I don't think is worth the effort.

So let's stick with the current naming scheme and do

config MDS
config TAA
...

and so on.

Thx.
