[PATCH v2 0/9] Hyper-V synthetic interrupt controller
This patchset implements the KVM part of the synthetic interrupt controller (SynIC) which is a building block of the Hyper-V paravirtualized device bus (vmbus). SynIC is a lapic extension, which is controlled via MSRs and maintains for each vCPU - 16 synthetic interrupt "lines" (SINT's); each can be configured to trigger a specific interrupt vector optionally with auto-EOI
