* remotes/mst/tags/for_upstream:
  tests/bios-tables-test: Fix endianess problems when passing data to iasl
  build-sys: restrict vmcoreinfo to fw_cfg+dma capable targets
  vmcoreinfo: put it in the 'misc' device category
  NUMA: Enable adding NUMA node implicitly
  tests/acpi-test-data: update _CRS in DSDT
  hw/pcie-pci-bridge: restrict to X86 and ARM
  hw/pci-host: Fix x86 Host Bridges 64bit PCI hole
  pci: Initialize pci_dev->name before use
  fix: unrealize virtio device if we fail to hotplug it
