'callr main' but there are two main?

In arch\nios2nommu\kernel\head.S,there is a piece of code like this:

callr main.

However,main function appeared two times in the kernel of linux.they are:

arch\nios2nommu\kernel\asm-offsets.c

arch\nios2nommu\kernel\start.c

And my question is, the 'callr main' of head.S call for which?The main function

in asm-offsets.c or the main function in start.c or anything else?

Thanks in advance!

    Sorry ,I made a mistake.The asm-offsets.c is useless in the kernel.
