[Qemu-devel] [PATCH 30/35] pc: ACPI BIOS: name CPU hotplug ACPI0004 device

[Igor Mammedov]

Following patches will add another ACPI0004 device
to the same scope, and that will make Windows BSOD
because it thinks that the second ACPI0004 device
is duplicate.
Adding to device unique _UID, fixes issue and allows
Windows to distinguish devices with the same _HID
