Message:

Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.
