How to set Stack/Heap Limit ?

Hello

I/We are trying to change the min of the stack to grow down, and max of heap to grow. Basically we want to try to use or reserve areas in this section.

Right now, we know that stacks occupies 4 pages for it to grow. And in relocate.S , its initialize like this :
.comm .stack,4096*2,4

Does anybody have any idea how to set the limit for both areas? like maybe compilation option ?

Thanks and hope for any insights

just found out where stack limit is defined :

linux/sched.h

#define _STK_LIM
