This series adds a kvm_device that acts as a irq controller for floating
interrupts. As a first step it implements functionality to retrieve and inject
interrupts for the purpose of migration and for hardening the reset code by
allowing user space to explicitly remove all pending floating interrupts.
PFAULT patches will also use this device for enabling/disabling pfault,
therefore
the pfault patch series will be reworked to use this device.
* Patch 1 adds a new data structure to hold interrupt information. The current
one (struct kvm_s390_interrupt) does not allow to inject all kinds of
interrupts,
e.g. some data for program interrupts and machine check interruptions were
missing.
* Patch 2 adds a kvm_device which supports getting/setting currently pending
floating interrupts as well as deleting all currently pending interrupts
