Pull virtio updates from Michael Tsirkin: "A small number of improvements all over the place: - vdpa/octeon support for multiple interrupts - virtio-pci support for error recovery - vp_vdpa support for notification with data - vhost/net fix to set num_buffers for spec compliance - virtio-mem now works with kdump on s390 And small cleanups all over the place" * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: (23 commits) virtio_blk: Add support for transport error recovery virtio_pci: Add support for PCIe Function Level Reset vhost/net: Set num_buffers for virtio 1.0 vdpa/octeon_ep: read vendor-specific PCI capability virtio-pci: define type and header for PCI vendor data vdpa/octeon_ep: handle device config change events vdpa/octeon_ep: enable support for multiple interrupts per device vdpa: solidrun: Replace deprecated PCI functions s390/kdump: virtio-mem kdump support (CONFIG_PROC_VMCORE_DEVICE_RAM) virtio-mem: support CONFIG_PROC_VMCORE_DEVICE_RAM virtio-mem: remember usable region size virtio-mem: mark device ready before registering callbacks in kdump mode fs/proc/vmcore: introduce PROC_VMCORE_DEVICE_RAM to detect device RAM ranges in 2nd kernel fs/proc/vmcore: factor out freeing a list of vmcore ranges fs/proc/vmcore: factor out allocating a vmcore range and adding it to a list fs/proc/vmcore: move vmcore definitions out of kcore.h fs/proc/vmcore: prefix all pr_* with "vmcore:" fs/proc/vmcore: disallow vmcore modifications while the vmcore is open fs/proc/vmcore: replace vmcoredd_mutex by vmcore_mutex fs/proc/vmcore: convert vmcore_cb_lock into vmcore_mutex ...
