I don't think you can win with any kind of abuse on ia64.  (For other
machines that only test the compat state of the task, any task will
do--though perhaps only test half the code.)  AFAICT, on ia64 only a real
empirical test can work at all.  That is, you must really be referring to a
task and its task_pt_regs() when that task really has entered the kernel
for a syscall.


Thanks,
