Merge remote-tracking branch 'remotes/mst/tags/for_upstream' into staging

pc,pci,virtio,qdev fixes, tests

new tests for SMBIOS
SMBIOS fixes
pc, pci fixes
qdev patches stayed on list for a month with no review,
as I told people on KVM forum I'm merging stuch patches
if they look fine.

Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

* remotes/mst/tags/for_upstream:
  qdev: Add test of qdev_prop_check_global
  qdev: Display warning about unused -global
  tests: add smbios testing
  tests: rename acpi-test to bios-tables-test
  virtio-balloon: return empty data when no stats are available
  pcie_host: Turn pcie_host_init() into an instance_init
  SMBIOS: Fix type 17 field sizes
  SMBIOS: Update Type 0 struct generator for machines >= 2.1
  SMBIOS: Fix endian-ness when populating multi-byte fields
  serial-pci: Set prog interface field of pci config to 16550 compatible
