I have managed to narrow it down to the newly allocated PTPs only, so
the current patch is more targeted
and performs the extra TLB invalidations only when a new PTP is being insta=
lled.
It seems KX-7000 either requires additional invalidation when new PTEs
are installed,
or some previously cached state isn't properly invalidated.
The patch should have a smaller performance impact, but it's not free eithe=
r.
