Applied with various tweaks as called out in the individual patch reviews

Note that this is queued up for 6.17 now as we are almost certainly too
close to the merge window (and hence not enough time in linux-next).

If the 6.15 release is delayed I might do another pull request.  If not
this will be on the togreg branch after I rebase on rc1. Until then pushed
out only as testing.

Thanks,

Jonathan
