Isnt it the other way around .... when the sys_* function is called .. the arguments are on the stack .... the syscall handler saves the register arguments (SAVE_ALL) and then invokes the actual syscall .... asmlinkage means that the arguments are on the stack and not in registers .... plz correct me if i am wrong.
