>>> Always add a cover letter, it makes it easier to follow the patchset, and you can also describe each change in the cover letter.

>>> When you send that other patch enabling ARM64, please add as many details as possible in the cover letter. Keep in mind that we have been working for isolating those FPU codes in a way that we do not regress any of our ASICs, which means that every change was well-tested on multiple devices. Anyway, maybe you can refer to this cover letter to write down the commit message:
