Mike Hibler did that for HPBSD and CSRG releases.
https://www.flux.utah.edu/~mike/hpbsd/hpbsd.html
"In April 1989, with encouragement from CSRG, I started the
``new VM project,'' integrating the Mach 2.0 VM system[1] into BSD. This
was done in the context of our then current HPBSD. A reasonable
prototype was done by November 1989 when I talked about it at the
``Berkeley workshop'' in Boulder[2]. Development on the new VM code in
HPBSD continued off and on til May of 1990 when the VM code was merged
into CSRG's source tree (what was to become net2 and later 4.4bsd)."
