- Subject: fix i386 __set_thread_area fallback
- this code is only needed for pre-2.6 kernels, which are not actually
- supported anyway, and was never tested. the fallback path using
- SYS_modify_ldt failed to clear the upper bits of %eax (all ones due to
- SYS_set_thread_area's return value being an error) before modifying
- %al to attempt a new syscall.
