That commit just produces the warning (since it introduced the
apic_noop.c file) and probably has nothing directly to do with the
problem (as I said).

The relevant part of apic.h is:

static inline physid_mask_t default_apicid_to_cpu_present(int phys_apicid)
{
        return physid_mask_of_physid(phys_apicid);
}

Where physid_mask_of_physid() manipulates a physid_mask_t which contains
an array of unsigned longs that is BITS_TO_LONGS(MAX_APICS) long and
MAX_APICS is 32768.
