4lDO2 a166a1ebb2 For now, put ptr to pctl in TCB. 2024-07-09 15:00:57 +02:00
4lDO2 63509e75ce Use new signal ABI where 'actions' are in shmem. 2024-07-09 15:00:56 +02:00
4lDO2 71800d2b73 Fix spurious ign signal. 2024-07-09 15:00:56 +02:00
4lDO2 f28fe4a387 Use fetch_add instead of CAS when setting sigmask.

fair, but still).
