Is this to circumvent CONFIG_MODVERSIONS=n?

This seems like a situation that shouldn't happen.  When upgrading, the
installed version (make modules_install) should be matched (ie: a
modprobe won't work because the kernel `uname -r` directory changed).
Otherwise, a new build should be done by the developer that changed out
their kernel (because they are manually building OvS modules and
installing from the source tree).

I'm probably not understanding the use case.
