it replaces a static complied in DSDT MMIO region for CPU hotplug with one created at runtime leaving only truly static CPU hotplug related ASL bits in DSDT. It also puts CPU_HOTPLUG_RESOURCE_DEVICE into PCI0 scope and reserves resources from it, preparing for dropping manual hole punching in PCI0._CRS. Later it also would make easier to reuse current ACPI CPU hotplug on other targets. Also later it would be possible to move remaining CPU hotplug ASL methods into build_ssdt() and add all CPU hotplug related AML into SSDT only when CPU hotplug is enabled, further reducing ACPI tables blob if CPU hotplug isn't used. impl. detail: Windows XP can't handle /BSODs/ OperationRegion declaration in DSDT when variable from SSDT is used for specifying its address/length and also when Field declared in DSDT with OperationRegion from SSDT if DSDT is being parsed before SSDT. But it works just fine when referencing named fields from another table. Hence OperationRegion and Field declaration are moved to SSDT to make XP based editions work. PS: Later Windows editions seem to be fine with above conditions. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.
