When emulating a 32 bit Linux user-mode program on a 64 bit target we implement the llseek syscall in terms of lseek. Correct a bug which meant we were silently casting the result of host lseek() to a 32 bit integer as it passed through get_errno() and thus throwing away the top half. We also don't try to store the result back to userspace unless the seek succeeded; this matches the kernel behaviour. Thanks to Eoghan Sherry for identifying the problem and suggesting a solution.
