    Walleij: How the ARM32 kernel starts
    Linus Walleij continues
    his exploration     of the boot process for the 32-bit Arm kernel.
    "BAM! The MMU is on. The next instruction (which is incidentally an
    instruction cache flush) will be executed from virtual memory. We don’t
    notice anything at first, but we are executing in virtual memory. When we
    return by jumping to the address passed in r13, we enter
    __mmap_switched at the virtual memory address of this function,
    somewhere below PAGE_OFFSET (typically 0xC0nnnnnn). We
    can now facilitate absolute addressing: the kernel is executing as
    intended.    "
