• Start to dive into interrupts in the Linux kernel - this part starts to describe interrupts and exceptions handling related stuff from the early stage.
• Early interrupt handlers - third part describes early interrupt handlers.
• Interrupt handlers - fourth part describes first non-early interrupt handlers.
• Implementation of exception handlers - descripbes implementation of some exception handlers as double fault, divide by zero and etc.
• Handling Non-Maskable interrupts - describes handling of non-maskable interrupts and the rest of interrupts handlers from the architecture-specific part.
