Software that was compiled with additional fences may have to be recompiled to remove them.

- starspangled 1y agomitigations=off disables workarounds for bugs or "mis-features" in the CPU that could be exploited to bypass OS security measures. smap is an OS security measure, and so does not get disabled by mitigations=off. smap can be pretty draining for certain IO performance though. IMO it should be more well-known or covered by a more obvious option. Linux kernel developers are really bad at defining and naming options like this.
