We need to choose one or the other. If we're going to have global macros
for compatibility, we need to provide one for ovbcopy. If not, we need to
nuke them all.
The latter case is not feasible at this moment, and hence, we need an
ovbcopy macro if we are to preserve the non-overlap meaning of bcopy() in
kernel. At least until we do deal with migration of all other code
(including imported code).
If I'm going to back out the change at this point, it'll be with the
addition of an ovbcopy macro, until such time that everything else is
