[Qemu-devel] [PATCH v2 0/2] KVM: s390: add floating irq controller

[Jens Freimann]

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 1/2 adds a new data structure to hold interrupt information. The current
  one (struct kvm_s390_interrupt) does not allow to inject every kind of 
interrupt,
  e.g. some data for program interrupts and machine check interruptions were
  missing.
 
* Patch 2/2 adds a kvm_device which supports getting/setting currently pending
  floating interrupts as well as deleting all currently pending interrupts
