Currently we only restore signals which are transactionally suspended but it's possible that the transaction can be restored even when it's active. Most likely this will result in a transactional rollback by the hardware as the transaction will have been doomed by an earlier treclaim. The current code is a legacy of earlier kernel implementations which did software rollback of active transactions in the kernel. That code has now gone but we didn't correctly fix up this part of the signals code which still makes assumptions based on having software rollback. This changes the signal return code to always restore both contexts on 32 bit rt signal return.
