[PATCH] virtio_pci: Clear stale cpumask when setting irq affinity
The cpumask vp_dev->msix_affinity_masks[info->msix_vector] may contain
staled information when vp_set_vq_affinity() gets called, so clear it
before setting the new cpu bit mask.

automatic IRQ affinity for virtio V2
Hi Michael, hi Jason,
This patches applies a few cleanups to the virtio PCI interrupt handling
code, and then converts the virtio PCI code to use the automatic MSI-X
vectors spreading, as well as using the information in virtio-blk
and virtio-scsi to automatically align the blk-mq queues to the MSI-X
vectors.
Changes since V1:
- dropped the patches already merged for 4.10-rc

[PATCH post-squash 0/9] virtio 1.0: virtio-pci fixup
This is just repost of all patches with fixups squashed in - convenient
if you just want to remove old ones from queue and apply new ones.
I also tweaked commit log for patch
"virtio_pci: modern driver"
I also included Gerd's tag:
