If it's only for some platforms and not others (due to causing regressions) then what is a distro supposed to do with their kernels that support multiple platforms? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
