xx_initcall ( ) in kernel

[sumeet linux]

Dear friends,

I want to know the basics xx_initcall ( ) in linux kernel. How this function
works ?
Observed in kernel code, many places late_initcall ( ), early_initcall ( ),
arch_initcall ( ), core_initcall ( ) gets called.
When did all these functions gets call during kernel initialization ?
I am more interested in what is the sequence of these functions gets called
one after another.

Thank you.

Regards,
Sumeet
