Local APIC - local APIC timer used as the source of time - PIC is still used as the hw interrupt controller as we don't have enough info without ACPI or MPS to set up IO APICs - remapping of APIC when switching paging on, uses the new mechanism to tell VM what phys areas to map in kernel's virtual space - one more step to SMP based on code by Arun C.

APIC mode uses IO APICs - kernel turns on IO APICs if no_apic is _not_ set or is equal 0 - pci driver must use the acpi driver to setup IRQ routing otherwise the system cannot work correctly except systems like KVM that use only legacy (E)ISA IRQs 0-15

/* The local APIC timer tick handlers */
SMP - Only a single APIC timer handler - bsp_timer_int_handler() and ap_timer_int_handler() unified into timer_int_handler() - global realtime updated only on BSP

_PROTOTYPE(void lapic_timer_int_handler, (void));
spurious and error interrupt apic handlers - fixed spurious and error interrupt handlers - not to hog the system the warning isn't reported every time, just once every 100 times, similarly for the spurious PIC interrupts
