Except for:

ia64-linux-ld: drivers/acpi/acpi_processor.o: in function `acpi_early_processor_control_setup':
acpi_processor.c:(.init.text+0x712): undefined reference to `acpi_proc_quirk_mwait_check'
ia64-linux-ld: drivers/acpi/processor_pdc.o: in function `acpi_early_processor_set_pdc':
processor_pdc.c:(.init.text+0x72): undefined reference to `acpi_proc_quirk_mwait_check'

which breaks all ia64 builds.

Time to retire that architecture yet ? No one but me seems to even
build test it.
