Since there was no feedback to my last post, I assume you agree, so please backout the tsc disable so then I can plug the performane counter disable on top of it (at zero additional runtime cost).
Also note: even if it may not be obvious because it's nicely hidden by header files, if you disable CONFIG_SECCOMP, the tsc disable patch becomes a noop and it's optimized away by gcc (like the rest of seccomp).
So if you don't want to risk the microslowdown in your systems, just disable SECCOMP and be done with it but please resurrect that patch so I can fix the performance counters too after that.
