[PATCH] Fix IA64 success/failure indication in syscall auditing.
Original 2.6.9 patch and explanation from somewhere within HP via bugzilla... ia64 stores a success/failure code in r10, and the return value (normal return, or *positive* errno) in r8. The patch also sets the exit code to negative errno if it's a failure result for consistency with other architectures. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
