[Qemu-devel] [PATCH v7 02/10] hw/pci-bridge: expose _test parameter in SHPC_VMSTATE()

[Laszlo Ersek <lersek@redhat.com>]

Change the signature of the function-like macro SHPC_VMSTATE(), so that we
can produce and expect this field conditionally in the migration stream,
starting with an upcoming patch.
