[Qemu-arm] [RFC v5 0/7] vITS support |

This series introduces support for in-kernel GICv3 ITS emulation.
It is based on a kernel API which is not yet released.
Tested on Cavium ThunderX with virtio-net-pci and vhost-net with both dt
and ACPI guests
Host Kernel dependencies:
- [PATCH v10 00/17] KVM: arm64: GICv3 ITS emulation
http://www.spinics.net/lists/kvm/msg135687.html
- [RFC v9 0/6] KVM: arm/arm64: gsi routing support
http://www.spinics.net/lists/kvm/msg136083.html
Guest Kernel dependencies for resp. ACPI ITS and PCIe support:
- [PATCH V7 0/8] Introduce ACPI world to ITS,
https://lkml.org/lkml/2016/6/20/321
- Support for ARM64 ACPI based PCI host controller,
https://lwn.net/Articles/690995/

This QEMU series can be found at:
v5: https://github.com/eauger/qemu/tree/v2.6.0-vITS-v5
Previous versions are available at:
v4: https://github.com/eauger/qemu/tree/v2.6.0-vITS-v4
v3: https://lists.gnu.org/archive/html/qemu-devel/2015-11/msg05197.html
History:
v4 => v5:
- fix compilation issue with arm-softmmu target
- rebase on target-arm: Fix unreachable code in gicv3_class_name()
- add ACPI support
- kernel ITS init sequence is not yet similar to GICv2/V3 ones. This will
be addressed in a subsequent respin.
v3 => v4:
- Took into account Peter's comments (at the exception of sub-class
operation changes)
- rebase on Andre's kernel ITS emulation series v8
- rework KVM init sequence and KVM device creation/settings overall.
I do not use kvm_arm_register_device due to the way the kernel
API is devises (see discussion on the kernel ML)
- change the computation of the GITS_TRANSLATER base address
- fix compilation issues
- new "arget-arm: move gicv3_class_name from machine to kvm_arm.h"
v2 => v3:
- Really added unmigratable flag, was overlooked in v2
- Fixed checkpatch issue with initializing static variable to zero
/bin/bash: indent : commande introuvabledded registers and reset method
- Added unmigratable flag
- Rebased on top of current master, use kvm_arch_fixup_msi_route() now
