Detailed Description
The interrupt subsystem.
The interrupt subsystem of StubBS contains all functionality to accept interrupts from the hardware and process them. In later exercises the interrupts will enable applications to execute core functionality (system calls). The entry point for the interrupt subsystem is the function 'interrupt_entry_VECTOR' (in interrupt/handler.asm).

High-Level Interrupt Handling.
Main interrupt handling routine of the system. This function is called by the corresponding interrupt_entry_VECTOR function (located in interrupt/handler.asm) with disabled interrupts.
- Parameters
-
vector number of the interrupt context Pointer to interrupt context (on stack).
