Tejun Heo acb8bc09c6 x86: Add apic->x86_32_early_logical_apicid() ... On x86_32, the mapping between cpu and logical apic ID differs depending on the specific apic implementation in use. The mapping is initialized while bringing up CPUs; however, this makes early inits ignore memory topology. Add a x86_32 specific apic->x86_32_early_logical_apicid() which is called early during boot to query the mapping. The mapping is later verified against the result of init_apic_ldr(). The method is allowed to return BAD_APICID if it can't be determined early. noop variant which always returns BAD_APICID is implemented and added to all x86_32 apic implementations.
