Subject: .exit.text section in vmlinux ?

Hi,

as far as I remember everything marked with __exit or __exit_data will only be 
used/called when unloading a module, and gets moved to the .exit.text or 
.exit.data sections.

Why are these sections present in the vmlinux/vmlinux.bin/bzImage and not 
dropped by the linker or at least objdump? 
This code will never be called for everything compiled in - in an allyesconfig 
build these sections account for ~80kb of code.

Is there something I'm missing here, or can we add "--remove-section 
.exit.data --remove-section .exit.text" to the OBJCOPYFLAGS for vmlinux?

Thanks,
Peter
