     NAME
          afs_syscall, break, fattach, fdetach, ftime, getmsg,
          getpmsg, gtty, isastream, lock, madvise1, mpx, prof, profil,
          putmsg, putpmsg, security, stty, tuxcall, ulimit, vserver -
          unimplemented system calls

     SYNOPSIS
          Unimplemented system calls.

     DESCRIPTION
          These system calls are not implemented in the Linux kernel.

     RETURN VALUE
          These system calls always return -1 and set errno to ENOSYS.

     NOTES
          Note that ftime(3), profil(3), and ulimit(3) are implemented
          as library functions.

          Some system calls, like alloc_hugepages(2),
          free_hugepages(2), ioperm(2), iopl(2), and vm86(2) exist
          only on certain architectures.

          Some system calls, like ipc(2), create_module(2),
          init_module(2), and delete_module(2) exist only when the
          Linux kernel was built with support for them.
