I did a patch for microblaze at some point, which turned out to be fairly

Thanks for doing this.
Apart from the sparc64 issue with completely separate address spaces
(so access_ok() should always return true like Al pointed out), this
looks excellent to me.
Somebody should check that there aren't other cases like sparc64, but
let's merge this asap other than that.
