I think I mostly agree, except for reverting 6060e8df5178, which I don't think would be correct. That reintroduces the possibility of flushing the I-cache twice in that path, once for aliasing vipt dcaches, and again for asid tagged vivt icaches. I'd rather have the code structured so we only do this once. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net.
