If CONFIG_ACPI is no then arch/ia64/kernel/mca.c drops the CPE handler,
but not the CMC handler. Also the CPE handler uses
acpi_request_vector(), but CMC does not. Why the differences?

Probably a bug, because we could still poll for CPEs w/o ACPI.
Originally the CPE handler was only interrupt driven and the interrupt
is described as a platform interrupt source via ACPI. So it made sense
then. CMC have never had an ACPI dependency since the architecture
defines their setup and not the platform.
