quick questions: kernel stack size and call gates

1. Does Linux use call gates (as specified in the Intel SDK vol.3) when a user process makes a system call? From what I understand, call-gates let a ring-3 process execute ring-0 code, which sounds exactly like a system call. I've found all of the actual system call functions (sys_ni etc.) in sys
