I'm not using quilt but git.

Unfortunatelly size changed:
paolo@paolo-desktop:/tmp$ size profile.o
text data bss dec hex filename
3718 144 12 3874 f22 profile.o
paolo@paolo-desktop:/tmp$ size profile.o.after
text data bss dec hex filename
3693 144 12 3849 f09 profile.o.after

I'll post the patch for review in a minute.

Thanks.

Ciao,
