It's easy enough to change "irqchip/gic-v3: Add support for ACPI's disabled but 'online capable' CPUs" to use Lorenzo's name when that patch hits - and it becomes one less patch in this patch set when Lorenzo's change eventually hits mainline. Does anyone know how long it may take for Lorenzo's change to get into mainline? Would it be by the 6.8 merge window or the following one? Thanks. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
