Interrupt and Exception Handling

New year, new topics! We are going to look into how interrupts and interrupt handling (and virtualization security) work in a x86 platform. While reading is very importantˆtm, we will also implement a Linux kernel module (a new one!) that hooks the interrupt table. Yeap yeap...! :)
