Subject: make initkmem_list3 non init data to fix modpost warning
From: Vivek Goyal <vgoyal@xxxxxxxxxx>
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.
