The flag newly added by ~~JDK-8312182~~ is prompting the use of `-XX:+DisableTHPStackMitigation` to disable the THP stack mitigation, thus allowing THP in thread stacks. This double negation does not read well, and not in line with other mitigation flags like `IntelJccErratumMitigation`.

It would be better to rename the flag to avoid double-negation, before it proliferates to other JDK releases.
