In this case, you should reconsider putting the string functions into
the vDSO. This will push the implementation to the kernel, but it
does more than just shifting the work: the kernel has more direct
means to provide hardware capabilities, and it also can use
just-in-time code generation (which we want to avoid in glibc).
Thanks,
