A few changes regarding the Guest's memory. The regs page must be mapped in Guest's page tables. I have put them on top of the RW area. In the same time, the offset where the stack will be placed needs to be updated. I have made the necessary changes for switch_to_guest part in the Switcher, but the rest of them needs to be done later. I have just commented the buggy lines where the LG_CPU_regs offset was used and they need to be corected when the code will get there.
