 *
 * Legacy PIC
 * ----------
 * * 0x20-0x27 disabled pic

 * 
 * Hardware Interrupts
 * -------------------
 * This interrupts are remapped by the IOAPIC
 *
 * * 0x0 PIT Timer -> 0x90
 * * 0x1 Keyboard  -> 0x91
 * * 0xC Mouse     -> 0x92
 *
 * Local Interrupts from LAPICs
 * ----------------------
 * * 0x8C APIC Timer
 * 
 * Software Interrupts
 * -------------------
 * * 0x80 System Call
 * * 0x81 IPI
 *
 * Usage
 * -----
 *
 *  Run interrupts_init() once first with the desired selector, usually 0x08.
 *  After that you can install the interrupts on each cpu via interrupts_install.
 *  interrupt_handler() and exception_handler() will be called accordingly from 
 *  the interrupt handlers this functionality is backed by. You can find them 
 *  in asm_int.h
