No it is not. See below.

This change adds an enum entry in a generic header file. _ALL_ users of
clock events have a switch(this_changed_enum) in the set_mode()
function. _ALL_ of them will spit warnings and some of them will even
break, when the fix up is not done in one go.

It's possible, but results in an commit which will affect bisecting. I'm
not going to send a patch which knowingly breaks bisecting either at
compile or at run time.

Oh, well. That's going to be an interesting feature for git and the
result will be published kernel trees with a total delta of 40MB against
mainline, because someone tweaked the stuff in a way that it contains
only the relevant files for a particular sub architecture. Embedded
folks do this already and it makes it extremely hard to do efficient
trouble shooting on such crippled trees. No thanks.
If we would still have 9600 Baud modem connections I would understand
that, but git is really effective since packing was added, so this
argument is more or less an academic exercise.
