[PATCH 1/6] indirect: use asmlinkage in i386 syscall table prototype
call_indirect() was using the wrong calling convention for the system call handlers. system call handlers would get mixed up arguments.

As it happened, Jens beat you to it :). Both problems have been fixed in the git repositories for the guilt series and userspace tools, respectively. You can always fetch the most recent versions from there. - z -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
