[BUG] The syscall argument registers are misleading in syscalls part one

In part two (https://0xax.gitbooks.io/linux-insides/content/SysCall/linux-syscall-2.html section "Preparation before system call handler will be called") its clear that for example ECX is not used as an argument register since RIP is stored in it. However in part 1 of the syscall series: This is the order used when calling functions yes, but not when calling syscalls. Also I think syscalls don't take arguments from the stack.
