This was purposely decided to be included unconditionally as the only
argument against making them conditional is code size. But, these
being very small functions it shouldn't matter all that much.
I had left this open for discussion. Since I did not hear any
preferences, I will make these conditional as Arnd and I discussed.

No, this should not be combined with patch 5. The purpose of that
patch is not to include all the code that is conditional upon that
config.
