How to find the stack address in x86 architecture?

Question

assembler

Hello.
In my kernel, I need to find the range in which the stack is located.
In the .text section, I configure esp like this:
mov esp, stack_space
And in the .bss section, I reserve space for the stack

section .bss
resb 8192
stack_space:

The complete code can be found here

Now, I need to find the address where the stack starts.
I know that it grows down, which means if its address is for example 0x3000, and the size allocated using resb is 2KB, then the range in which the stack is located will be 0x1000 - 0x3000, right?
But how can I find his address?

Put a mark in the right place. Load label address into register

section .bss
stack_bottom:
resb 8192
stack_top:
.text
mov eax, stack_bottom
