x86: modify get_desc_base
This patch makes get_desc_base() receive a struct desc_struct, and then uses its internal fields to compute the base address. This is done at both i386 and x86_64, and then it is moved to common header Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
