For my x86_64 usualconfig .text (from objdump --headers) went from
0x002c55c7 down to 0x002c2bda, which is 10.5k saved.

According to /usr/bin/size, vmlinux got bigger:

box:/usr/src/25> size vmlinux
text data bss dec hex filename
3597448 716340 510456 4824244 499cb4 vmlinux-before
3640604 716228 510456 4867288 4a44d8 vmlinux-after

But that's because size(1) is too blunt an instrument: the sum of .text and
the new bug section got larger.

I think we need to thank the powerpc guys, then take away their function
name printing ;)
