New definitions are added for CEX3 device types. They will be set in the according probe functions. CEX3 device types will be handled in the same modules as CEX2 device types. In the first step they are the same as CEX2 types, but they can be adjusted for further characteristics of CEX3 easily.

Support for special command is implemented in the AP Bus in the NQAP function __ap_send. This is extended for a further parameter special. When set, the special bit, in GR0 will be set. Therefor the ap_message struct is extended for a further bit. Thus calling functions of __ap_send can use the special parameter in ap_message to give to __ap_send. Affected is in the first place ap_queue_message, which is called by the actual card driver. The second part of this support is that the card driver for the CEX3C needs to set this special bit, when an according CPRB is sent to the driver.

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.

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: NFelix Beck <felix.beck@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.
