I wrote a patch for this, applying onto a vanilla 2.4 kernel tree, but I ne= ver=20 tested it (not even if it compiled). And I'm rechecking it, and there are=20 some bugs in it. About your patch, there is just a big bug in your patch (if you want to run= a=20 *32* bit UML): when a 32 bit app invokes a syscall, let's say mmap, actuall= y=20 it calls the sys32_ version of it, if that one exists, in this case=20 sys32_mmap. You can check the name of the syscall functions in=20 arch/x86_64/ia32/ia32entry.S. There are some such bugs in my patch, too, in= =20 fact. However, when I come back (I'm on holidays and far from Internet -=20 today is 23 August), if you want to help (i.e. actually test the patches), = just email me and I'll finish the porting and publish it. --=20 Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
