Learning Solaris Internals : Memory Paging

I am learning from the first edition of Solaris Internals, where the following is stated, talking about a user process:

“Initially, a single page is allocated for the stack, and as the process executes and calls functions, it pushes the program counter, arguments, and local variables onto the stack. When the stack grows larger than one page, the process causes a page fault, and the kernel notices that this is a stack segment page fault and grows the stack segment.”

I wanted to verify this first statement:

Anyways, in summary we see that the pagesize is 8KB and the Stack is mapped one page as shown from pmap output.
