Re: [PATCH net-next v2] sections: global data can be in .bss

When checking an address is located in a global data section also check
for the .bss section as global variables initialized to 0 can be in
there (-fzero-initialized-in-bss).

This was found when looking at ensure_safe_net_sysctl which was failing
to detect non-init sysctl pointing to a global data section when the
data was in the .bss section.

A few remarks:

- This still targets net-next but I added Arnd if he prefers to take it
  through the 'asm-generic' tree, now that is_kernel_core_data is in
  include/asm-generic/.

I have nothing else for asm-generic at the moment, please take
this through net-next.
