KVM: s390: interface for suppressible I/O adapters
In order to properly implement adapter-interruption suppression, we
need a way for userspace to specify which adapters are subject to
suppression. Let's convert the existing (and unused) 'pad' field into
a 'flags' field and define a flag value for suppressible adapters.
Besides, add documentation for the interface.
