    Subject[PATCH 21/25 -v2] export cpu_gdt_descr
    With paravirualization, hypervisors needs to handle the gdt,
    that was right to this point only used at very early
    inialization code. Hypervisors are commonly modules, so make
    it an export

    [ updates from v1
    * make it an EXPORT_SYMBOL_GPL.
