[PATCH] Fix topology.c location
When compiling a non-default subarch, topology.c is missing from the kernel
build. This causes builds with CONFIG_HOTPLUG_CPU to fail. In addition,
on Intel processors with cpuid level > 4, it causes intel_cacheinfo.c to
reference uninitialized data that should have been set up by the initcall
in topology.c which calls register_cpu. This causes a kernel panic on boot
on newer Intel processors. Moving topology.c to arch/i386/kernel fixes
both of these problems.
Thanks to Dan Hecht for finding and fixing this problem.
