[PATCH 0/3] workaround Windows always reading _DSM(func=7)

[Igor Mammedov <imammedo@redhat.com>]

subj causes PCI devices that do not have acpi-index assigned,
having bogus 'PCI Label Id = 0'.

The later triggers another Windows bug that leads to guest hang
in case of localized Windows versions [1].

Workaround is for QEMU to return invalid Package on _DSM(func=7) request
if acpi-index is not configured, which makes Windows ignore returned value
and not assign 'PCI Label Id'.

It should help [1] users to boot localized Windows variants as long as
no PCI devices have acpi-index explicitly assigned.
