This series introduces several improvements to the function that performs
AP queue resets:

* Breaks up reset processing into multiple smaller, more concise functions.

* Use TAPQ to verify completion of a reset in progress rather than mulitple
   invocations of ZAPQ.

* Check TAPQ response codes when verifying successful completion of ZAPQ.

* Fix erroneous handling of some error response codes.

* Increase the maximum amount of time to wait for successful completion of
   ZAPQ.
Change log v1 => v2:
-------------------
Remove patch 7/7 to restore original behavior since we don't know whether
interrupts are disabled when an unexpected response code is returned from
ZAPQ. (Halil)

Tony Krowiak (6):
   s390/vfio-ap: verify reset complete in separate function
   s390/vfio_ap: check TAPQ response code when waiting for queue reset
   s390/vfio_ap: use TAPQ to verify reset in progress completes
   s390/vfio_ap: verify ZAPQ completion after return of response code
     zero
   s390/vfio_ap: fix handling of error response codes
   s390/vfio_ap: increase max wait time for reset verification

Thanks applied and queued for CI and regression runs. Will likely go via s390 tree.
