Note that the stack is per-thread. The concept is somewhat machine-specific, some architectures utilize two stacks, on some the stack is purely software convention. You did not specified what context your code is to be run, e.g. is it kernel or user space ? Assuming it is kernel since you mentioned vm_something. The least error prone route is the thread context (frame) -> tf_esp on i386 (or tf_rsp on amd64) -> lookup of the map entry in the process p_vmspace. In reality, the stack is often fragmented, since the stack grow code does not coalesce the adjacent grow-down map entries.
