Currently _edata does not include several data sections, this causes
the kernel's report of memory usage at boot to not match reality, and
also prevents kmemleak from working - because it scan between _sdata
and _edata for pointers to allocated memory.
This mirrors a similar change made recently to the x86 linker script.
