[Qemu-devel] [PATCH 5/9] pc: PIIX DSDT: exclude CPU/PCI hotplug & GPE0 IO range from PCI bus resources

[Igor Mammedov]

.. so that they might not be used by PCI devices.

Note:
Resort to concatenating templates with preprocessor help,
because 1.0b spec isn't supporting ConcatenateResTemplate,
as result Windows XP fails to execute PCI0._CRS method if
ConcatenateResTemplate() is used.

Follow up patch will expose them as motherboard resources
