Attempt [1] to fix I/O allocation with the 'reserve-io' hint on each
pcie-root-port resulted in regression [2-3]. This patchset aims to fix
it by addressing the root cause of the problem - the disabled PCIe
Slot HPC bit.

Julia Suvorova (5):
  hw/pci/pcie_port: Rename 'native-hotplug' to 'native-hpc-bit'
  hw/acpi/ich9: Add compatibility option for 'native-hpc-bit'
  bios-tables-test: Allow changes in DSDT ACPI tables
  hw/i386/acpi-build: Deny control on PCIe Native Hot-plug in _OSC
  bios-tables-test: Update golden binaries
