Dave Kessler from Team Vanir on the subject of the Moto X Dalvik/Bionic patches floating around XDA at the moment:
They aren't compatible with your device unless the rest of the rom was compiled from the same source. If you like memory alignment segmentation faults continue to use them.
They are a bunch of snake oil bull**** anyways. On my nexus 5 they increased quadrant scores from ~10,000 to ~20,000. HUGE red flags here lol. Don't you think any device that uses them would have gotten a lot more press just because they were using them if they actually did something? it's easy to insert hacks to increase benchmark scores and it's something we've chosen to not do. We even removed the ones from the linaro source we rebased.
Just another perspective. Don't get too hung up on the inclusion of these patches in whatever ROM you're using. CM have included their own bionic optimisations and PA have done the same.
