Subject[PATCH v2] x86/devicetree: Fix build for amd64
Date
apic_force_enable is not defined for amd64.

Without this patch:

LD init/built-in.o
arch/x86/built-in.o: In function `dtb_lapic_setup':
kernel/devicetree.c:155:
undefined reference to `apic_force_enable'
Makefile:923: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1

Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com>

v2: Suggested by: Jiang Liu <jiang.liu@linux.intel.com>

How about defining a version of apic_force_enable()
for X86_64 in apic.h which just return failure?
