Well, my posts to the mailing list from my usual address have been
rejected a couple of weeks ago due to smtp authentication issues it
seems, which are now (mostly) sorted out, I thought you did receive this
reply as a direct recipient though. Looks like you did not. So here it
is.

PS: Since this reply was written, the x86 status with respect to the
Dovetail port to v6.8-rc7 has improved. Still in the process of
rewriting the arm64/fpsimd stuff.
