[PATCH 21/25 -v2] export cpu_gdt_descr

[Glauber de Oliveira Costa]

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.
   Suggested by Arjan van de Ven
]
