x86: make 64bit have get_apic_id
generalize the x2apic code some more. let read_apic_id become a macro (later on a function/inline) GET_APIC_ID(apic_read(APIC_ID)) +#define read_apic_id() (GET_APIC_ID(apic_read(APIC_ID))) instead of this weird construct: -#define read_apic_id (genapic->read_apic_id) Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Cc: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
