32-bit hobby kernel.

It aims to implement the basic features of a kernel: paging, usermode, basic syscalls, scheduling.

For the moment there is little interaction that is possible. I will try to implement a shell when the rest is a bit more developed.

The memory is subdivided in this way for programs loaded in user mode:

|Memory region  | Address

|---------------|------------

|Kernel code    | ``0x00100000``

|Kernel data    | ``0x00200000``

|Kernel stack   | ``0x00800000``

|User data      | ``0x10000000``

|User code      | ``0x20000000``

|User stack     | ``0x28000000``
