[PATCH v2 00/20] pci-assign: Refactor for upstream merge

[Jan Kiszka <jan.kiszka@siemens.com>]

With this series, we are getting very close to obsoleting qemu-kvm. It
refactors hw/device-assignment.c and the associated KVM helper functions
into a form that should allow merging them into QEMU. Once the series is
acceptable for qemu-kvm, I will break out the necessary uq/master
patches and push pci-assign to upstream.

The major step of this series is to define a regular set of kvm_device_*
services that encapsulate classic (i.e. KVM-based, non-VFIO) device
assignment features and export them to i386 targets only. There will
never be another arch using them, therefore I pushed them into this
corner. Moreover, the device assignment device now makes use of the new
KVM IRQ/MSI routing API and no longer pokes into the internals of that
layer. Finally, I moved the code into hw/kvm/pci-assign.c, dropped the
superfluous configure option and did some basic code cleanups (mostly
coding style) to bring things in shape.

Note that patch 1 is a simple bug fix that should likely be applied for
qemu-kvm-1.2 independently.

Changes in v2:
 - rebased over qemu-kvm next
 - consistently clear unused IOCTL fields via structure initialization

Jan Kiszka (20):
  pci-assign: Only clean up registered IO resources
  pci-assign: Factor out kvm_device_pci_assign/deassign
  pci-assign: Rename assign_irq to assign_intx
  pci-assign: Refactor interrupt deassignment
  pci-assign: Factor out kvm_device_intx_assign
  qemu-kvm: Move kvm_device_intx_set_mask service
  qemu-kvm: Clear unused IOCTL fields in kvm_device_intx_set_mask
  pci-assign: Rework MSI assignment
  pci-assign: Factor out kvm_device_msix_supported
  pci-assign: Replace kvm_assign_set_msix_nr with
    kvm_device_msix_init_vectors
  pci-assign: Replace kvm_assign_set_msix_entry with
    kvm_device_msix_set_vector
  pci-assign: Rework MSI-X route setup

  qemu-kvm: Kill qemu-kvm.[ch]
  pci-assign: Drop configure switches
  pci-assign: Move and rename source file
  pci-assign: Fix coding style issues
  pci-assign: Replace exit() with hw_error()
  pci-assign: Drop unused or write-only variables
  pci-assign: Gracefully handle missing in-kernel irqchip support
