GIET_VM / Boot & Kernel common functions

The boot code and the kernel code are two separated compilation units, but some functions are used by both the boot code and the kernel code:

• They are used by the boot-loader in the static phase, to build the page tables and initialize the schedulers and the peripherals.
• They are used by the kernel in the dynamic phase, to handle events such as interrupts, exceptions and syscalls.
