It's put into struct apic::acpi_madt_oem_check - which is a non-init
structure. That particular field is only used from init context -
but other fields are used all the time.

Sam, what's the preferred way to handle these? We could mark the
function pointer prototype there as __initdata, but i suspect we'll
still get the warning in that case.
