  virtio-console: avoid DMA from stack (2017-03-02 01:35:06 +0200)

----------------------------------------------------------------
virtio, vhost: optimizations, fixes

Looks like a quiet cycle for vhost/virtio, just a couple of minor
tweaks. Most notable is automatic interrupt affinity for blk and scsi.
Hopefully other devices are not far behind.

Christoph Hellwig (9):
      virtio_pci: remove struct virtio_pci_vq_info
      virtio_pci: use shared interrupts for virtqueues
      virtio_pci: don't duplicate the msix_enable flag in struct pci_dev
      virtio_pci: simplify MSI-X setup

      virtio: provide a method to get the IRQ affinity mask for a virtqueue
      blk-mq: provide a default queue mapping for virtio device
