Actually, there is already code present in the kernel which seem to be accessing some text in init.text sections. Because CONFIG_RELOCATABLE compiles the vmlinux with --emit-relocs options, these warnings become visible using MODPOST. So basically, these problems like accessing .init.data:boot_params from .text section already exist. Enabling CONFIG_RELOCATABLE, just makes them visible in the form of warnings. I will see how many of these I can get rid of.
