Also disable a couple of ACPI devices that are not usable under Dom0. To this end a couple of booleans are added that allow disabling ACPI specific devices. Sponsored by: Citrix Systems R&D Reviewed by: jhb x86/xen/xen_nexus.c: - Return BUS_PROBE_SPECIFIC in the Xen Nexus attachement routine to force the usage of the Xen Nexus. - Attach the ACPI bus when running as Dom0. dev/acpica/acpi_cpu.c: dev/acpica/acpi_hpet.c: dev/acpica/acpi_timer.c - Add a variable that gates the addition of the devices. x86/include/init.h: - Declare variables that control the attachment of ACPI cpu, hpet and timer devices.
