This is a repost of my patch series implementing in-kernel emulation of the XICS interrupt controller architecture defined in PAPR (Power Architecture Platform Requirements, the document that defines IBM's pSeries platform architecture). This version of the patch series uses the device API as posted by Scott Wood. I have structured the series so that the API is added by the last two patches, so as to be able to accommodate any future revisions to the device API with minimal changes. The series is based on Alex Graf's kvm-ppc-next branch with Scott Wood's recent patch series applied on top, together with the patch below to allow it to compile with CONFIG_KVM_MPIC=n. The API defined here uses KVM_CREATE_DEVICE to create the XICS, KVM_DEVICE_SET_ATTR/KVM_DEVICE_GET_ATTR to manipulate the interrupt sources (for initialization and migration), a new KVM_CAP_IRQ_XICS capability to connect vcpus to the XICS, a new identifier KVM_REG_PPC_ICP_STATE for the one-reg interface to get and set per-vcpu state, and the existing KVM_IRQ_LINE ioctl to assert and deassert interrupt sources.
