_end (end of kernel image how???)

["Sudharsan Vijayaraghavan" <sud_vijay@xxxxxxxxxxxxxx>]

Hi ,

Am new to LINUX Kernel. I was reading kernel/setup.c
It says that _end is end of the loaded kernel image.
I can find the symbol in vmlinux.lds.
However can some one clarify for me on where exactly it becomes
the end of kernel image.
In other words where exatcly mapping happens for the same.

I can find -e startup32 in compressed/head.S which shows it is starting of kernel along with head.o which maps to  _text = . in vmlinux.lds.

Please help me out.

Thanks,
Sudharsan.
