<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">Move Local APIC initialization, IPI, and utility functions out of smp-imps.c into a file bsps/i386/shared/irq/apic.c for lapic driver. This decouples the LAPIC driver from the MPS table parsing code.</p>

<li style="margin-top: 0; line-height: 1.6em; margin-left: 25px; padding-left: 3px;">Add apic.c with lapic_initialize(), lapic_enable(), lapic_send_ipi(), lapic_clear_errors(), lapic_reset_and_start_ap(), and lapic_reset_ap()</li>
<li style="line-height: 1.6em; margin-left: 25px; padding-left: 3px;">Extend apic.h with LAPIC register offset macros, inline helpers lapic_get_id() and lapic_send_eoi(), and function declarations</li>
<li style="line-height: 1.6em; margin-left: 25px; padding-left: 3px;">Replace IMPS_LAPIC_READ/WRITE macros with direct register access through the i386_lapic_base pointer</li>
<li style="line-height: 1.6em; margin-left: 25px; padding-left: 3px;">Replace imps_cpu_apic_map/imps_apic_cpu_map with i386_cpu_to_lapic_map/i386_lapic_to_cpu_map</li>
<li style="line-height: 1.6em; margin-left: 25px; padding-left: 3px;">Remove send_ipi(), imps_lapic_addr, and related globals from smp-imps.c and smp-imps.h</li>
