Because we have changed the structure of lg_cpu, the offset of rw data pointer in the structure is not 0 any more. That is why we need a new entry in asm_offset which will be used in switcher's code. In the same time, PRINT_NUM macro used for debugging can not use stack because the address stored in RSP is not valid any more after the page tables are changed.
