nouveau: ACPI support depends on X86 and X86_PLATFORM_DEVICES
If I build nouveau on ia64, Kconfig warns:
warning: (DRM_NOUVEAU) selects ACPI_WMI which has unmet direct dependencies (X86 && X86_PLATFORM_DEVICES && ACPI)
warning: (DRM_NOUVEAU) selects MXM_WMI which has unmet direct dependencies (X86 && X86_PLATFORM_DEVICES && ACPI_WMI)
Make all the ACPI support depend on X86 and select
X86_PLATFORM_DEVICES.
