+Subject: [PATCH] nouveau: ACPI support depends on X86 and X86_PLATFORM_DEVICES
+Forwarded: http://lists.freedesktop.org/archives/dri-devel/2013-February/035133.html
 
-The ACPI support code probably wasn't very useful on ia64, and now
-depends on mxm-wmi which is definitely x86-only.
+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.
