A quick whirl on my cats (with my favorite test: make cleandir; make
buildlink; time make configure for pkgsrc/devel/gmake)
gives the following times:
old pmap:
      176.56 real        74.60 user       120.59 sys
new pmap:
      149.15 real        75.67 user        93.10 sys

So it's most definetly faster.   I'll try and dust off my acorn32 and do
the needed work, and get figures together for that.

Hmmm, now I've a whole new arm32 pmap to learn 8)  Ooooh and I can close
a PR that complains about running out of L1 tables.

Nice work Steve.

Cheers,
