[Qemu-ppc] [PATCH 00/10] xics: Get rid of KVM specific classes

[Greg Kurz]

As recently pointed [1], using different object types for the KVM and
non-KVM scenarios was a bad idea: "In general different device types
should represent guest-visibly different objects, not just implementation
differences."

This series converts the base ICP class and the "simple" ICS class to
support KVM. This is done through the use of kvm_irqchip_in_kernel(),
which allows the compiler to optimize the KVM branches out when CONFIG_KVM
isn't set.

The removal of the KVM specific object types greatly simplifies the code.

Please comment.
