/**
* @brief "interrupt stack frame" (ISF)
*
* An "interrupt stack frame" (ISF) as constructed by the processor and the
* interrupt wrapper function _interrupt_enter(). As the system always
* operates at ring 0, only the EIP, CS and EFLAGS registers are pushed onto
* the stack when an interrupt occurs.
*
* The interrupt stack frame includes the volatile registers EAX, ECX, and EDX
* plus nonvolatile EDI pushed on the stack by _interrupt_enter().
*
* Only target-based debug tools such as GDB require the other non-volatile
* registers (ESI, EBX, EBP and ESP) to be preserved during an interrupt.
