Add the IAM (Interruption Alert Mask) to the architectue specific
kvm struct. This mask in the GISA is used to define for which ISC
a GIB alert can be issued.
The functions kvm_s390_gisc_register() and kvm_s390_gisc_unregister()
are used to (un)register a GISC (guest ISC) with a virtual machine and
its GISA.
Upon successful completion, kvm_s390_gisc_register() returns the
ISC to be used for GIB alert interruptions. A negative return code
indicates an error during registration.

I've started at this and the following patches and have not found a
place where the functions are called... leftover from a previous
version?
No, these functions are required by the related driver code.
Pls. see:

[v2,3/3] vfio: ap: AP Queue Interrupt Control VFIO ioctl calls
I guess they should go with that series, then.
No, I don't think so. These functions are part of the
*GIB infrastructure* and will by consumed e.g. by VFIO AP
with irqs but also by PCI.
