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

Good, that's what we'd hope for. It's going to be a bigger overall than the previous i386 code, because it's now saving away the EIP as well as filename* and line for each BUG.

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

size -A will tell you everything you ever wanted to know.

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

I think so...
