No code changed:

  # arch/x86/kernel/apic/apic_flat_64.o:

   text    data     bss     dec     hex filename
   1838     624       0    2462     99e apic_flat_64.o.before
   1838     624       0    2462     99e apic_flat_64.o.after

md5:
   aa2ae687d94bc4534f86ae6865dabd6a  apic_flat_64.o.before.asm
   42148da76ba8f9a236c33f8803bd2a6b  apic_flat_64.o.after.asm

md5 sum is different due to asm output offsets changing.
