[PATCH 00/20] qemu-kvm: vhost net port

[Michael S. Tsirkin]

This is port of vhost v1 patch set I posted previously to qemu-kvm, for
those that want to get good performance out of it :)
This includes irqchip support and merge fixup on top of upstream patch.

Michael S. Tsirkin (20):
  exec: memory notifiers
  kvm: move kvm_set_phys_mem around
  kvm: move kvm to use memory notifiers
  qemu-kvm: fixup after merging memory notifiers
  kvm: add API to set ioeventfd
  notifier: event notifier implementation
  virtio: add notifier support
  virtio: add APIs for queue fields
  virtio: add status change callback
  virtio: move typedef to qemu-common
  virtio-pci: fill in notifier support
  tap: add interface to get device fd
  vhost: vhost net support
  tap: add vhost/vhostfd options
  tap: add API to retrieve vhost net header
  virtio-net: vhost net support
  qemu-kvm: add vhost.h header
  kvm: irqfd support
  msix: add mask/unmask notifiers
  virtio-pci: irqfd support
