Lionel Debroux 9e67c35a1c WIP BROKEN NX enablement, for now only for the second page directory.
TODO:
    * selective NX enablement on pd0, pd1 and pd3.
      Unconditional NX on the whole pd3 makes memtest86+ reboot in a QEMU-emulated computer.
    * if supported on all x86_64 CPUs, simply enable long mode and NX simultaneously ? A real K8 dual-core processor didn't seem to hate it, at least.
    * startup code: NX enablement for x86, on capable computers (CPUID 0x80000001, edx bit 20).
    * set the appropriate flag in the headers.
