[PATCH 2/4] make initkmem_list3 non init data to fix modpost warning

[Vivek Goyal]

o MODPOST generates warning for i386 if kernel is compiled with
  CONFIG_RELOCATABLE=y

WARNING: vmlinux - Section mismatch: reference to .init.data:initkmem_list3 from .text between 'set_up_list3s' (at offset 0xc01536d9) and 's_start'

o I don't know the code well but looks like this is a bug.  initkmem_list3
  is of type __initdata, and it is accessed by non init functions.

	kmem_cache_create()
		setup_cpu_cache()
			set_up_list3s()
				{
					Accesses initkmem_list3[]
				}

o Somebody who knows this code well needs to review and ack.
