* [S390] zcrypt: Do not add/remove devices in s/r callbacksFelix Beck2009-09-221-11/+29
| | | | | | | | | | | | | | Devices are no longer removed or added in the suspend and resume callbacks. Instead they are marked unregistered in suspend. In the resume callback the ap_scan_bus method is scheduled. The bus scan function will remove the old device and add new ones. This way all the device handling will be done in only one function. Additionaly the case where the domain might change during suspend/resume is caught. In that case the devices qid needs to re-calculated in order of having it found by the scan method.

* [S390] zcrypt: fix scheduling of hrtimer ap_poll_timerFelix Beck2009-07-241-2/+7
| | | | | | | | | | | | Every time a request is enqueued or there is some work outstanding from the ap_tasklet, the ap_poll_timer is scheduled again. Unfortunately it was permanently called. It looked as if it was started in the past and thus imediately expired. This has been changed. First it is checked if the hrtimer is already expired. Then the expiring time is forwarded and the timer restarted. Signed-off-by: Felix Beck <felix.beck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
