Confused. ARM (32-bit) or ARM64? You patch 32-bit ARM, but you don't touch 64-bit Arm. "ARM" on its own in the context above to me suggests 32-bit, since you refer to ARM64 later. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
