Hi Miles,
Yes these warnings appear if CONFIG_RELOCATABLE is enabled. 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.
Thanks
Vivek
