2021-05-04	virtio_pci_modern: correct sparse tags for notify	Michael S. Tsirkin	1	-2/+2
	When switching virtio_pci_modern to use a helper for mappings we lost an __iomem tag. Restore it. Reported-by: kernel test robot <lkp@intel.com> Fixes: 9e3bb9b79a71 ("virtio_pci_modern: introduce helper to map vq notify area") Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2021-05-03	virtio-pci library: report resource address	Jason Wang	1	-1/+3

2021-05-03	virtio_pci_modern: hide vp_modern_get_queue_notify_off()	Jason Wang	1	-2/+0
	All users (both virtio-pci library and vp_vdpa driver) has been switched to use vp_modern_map_vq_notify(). So there's no need to export the low level helper of vp_modern_get_queue_notify_off().
