What I would really like to know is why having to run _code_ to work out what the page protections need to be is better than looking it up in a table. Not only is this more expensive in terms of CPU cycles, it also brings additional code size with it. I'm struggling to see what the benefit is. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
