Well, I used to believe that. After looking at do_fork() and sys_clone(), it appears the location of the new stack is actually being passed into sys_clone() in the pt_regs argument?!?!? That's very weird; the kernel has to allocate space for a new task's stack somewhere. In fact I notice all the sys_*() functions get a pt_regs argument; where does that come from, what does it mean? I'm not sufficiently clueful about gas assembler syntax to have any idea what the code in entry.S (system_call) is doing. Can anyone clarify how this works?
