Note that, even though I haven't posted an update (I see it as mostly pointless because *noone* commented on the previous posting) I do maintain these patches: git://git.armlinux.org.uk/~rmk/linux-arm.git aarch64/ktext/head currently has them against v6.7 -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
