The __SYSCALL macro's arguments are system call number, system call entry name and number of arguments for the system call. Argument- nargs in __SYSCALL(nr, entry, nargs) is neither calculated nor used anywhere. So it would be better to keep the implementaion as __SYSCALL(nr, entry). This will unifies the implementation with some other architetures too. Signed-off-by: Firoz Khan <firoz.khan@linaro.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
