Yes, the sys_* funcs are declared asmlinkage int sys_*.
where the asmlinkage differ from platform to platform.
It's used to tell the compiler if a non standared calling
convertion is used, typically if params are passed by registers
instead of stack. The asmlinkage define must be sett according to the
syscall dispatcher (entry.S on ia32), and may be changed accordingly.
In short, if you want to use sys_* you must understand the interaction
between the sys_* funcs and the dispatcher on *every* platform, and
the interaction may change without notice.
In short short, don't don't don't don't use the sys_* functions.
