* remotes/mst/tags/for_upstream:
tests: update acpi expected files
vhost: fix invalid downcast
pc: make sure that guest isn't able to unplug the first cpu
hw/pci: add PCI resource reserve capability to legacy PCI bridge
hw/pci: factor PCI reserve resources to a separate structure
virtio: update MemoryRegionCaches when guest negotiates features
pc: acpi: revert back to 1 SRAT entry for hotpluggable area
