It's still weird: I copied your config to 4d7321381e5c and made 'make oldconfig' - 
and it asked a couple of questions, which suggests that your config does not come 
from 4d7321381e5c?

Furthermore, building 4d7321381e5c and 4d7321381e5c^1 gives me:

  # arch/x86/entry/entry_64.o:

   text    data     bss     dec     hex filename
  11530       0       0   11530    2d0a entry_64.o.before
  11530       0       0   11530    2d0a entry_64.o.after

md5:
   1430e793250d5d8572bc2df2997d3929  entry_64.o.before.asm
   1430e793250d5d8572bc2df2997d3929  entry_64.o.after.asm

i.e. I have trouble reproducing the discrepancy you are seeing. (I also tried 
allmodconfig/allyesconfig again for good measure - no luck.)

Thanks,

	Ingo
