This line needs to be changed to refer to omap2plus_defconfig.

I guess this data is probably stale as well. Here is the before and
after numbers using omap2plus_defconfig on v4.11-rc2

before:
   text	   data	    bss	    dec	    hex	filename
8186930	3082444	8252992	19522366	129e33e	vmlinux

after:
   text	   data	    bss	    dec	    hex	filename
8186922	3084812	8252992	19524726	129ec76	vmlinux

The size increase remains at ~2.3K in data section.

Thanks,
