Subject: [PATCH v4 0/3]  a couple of corrections to the IRQ enablement function

This series corrects two issues related to enablement of interrupts in 
response to interception of the PQAP(AQIC) command:

1. Returning a status response code 06 (Invalid address of AP-queue 
   notification byte) when the call to register a guest ISC fails makes no
   sense.
   
2. The pages containing the interrupt notification-indicator byte are not
   freed after a failure to register the guest ISC fails.

Change log v3 ==> v4:
--------------------
* Improved commit message in patch 2/3 (Halil)

Anthony Krowiak (2):
  s390/vfio-ap: unpin pages on gisc registration failure
  s390/vfio-ap: set status response code to 06 on gisc registration
    failure

Tony Krowiak (1):
  s390/vfio-ap: improve reaction to response code 07 from PQAP(AQIC)
    command
