So how to access different areas(.i.e > data,text) in kernel stack. I think you got a wrong understanding of the stack. The stack has no separate bss, data, and text sections, it's just a stack of function arguments, local variables, and return addresses. Accessing the stack works automatically: call a function, and the function paramaters and the return address are pushed on the stack. Unless you have a *very* good reason, there is no need to manipulate the stack directly in kernel mode.
