I agree with this as a general rule, but for this (hopefully never to be repeated) operation, it makes sense to me to keep each change in this set as one patch. For the simple reason that the alternative leaves several unusable commits in sequence in the repository. There is simply no way to bisect through this change on a per-package basis. This is after all a horrible horrible hack that lets us keep using the .asm files provided for one toolchain family (RVCT) in a different toolchain family (MSFT), without having to delete and re-add, losing history in the process.
