      18  /* Some architectures have irregular system call names in
      19     <asm/unistd.h>.  glibc assumes that system call numbers start with
      20     __NR_* and lists the system calls under proper names in
      21     <arch-syscall.h>.
      22  
      23     During consistency tests, <fixup-asm-unistd.h> is included after
      24     the kernel's <asm/unistd.h>, to introduce aliases as necessary to
      25     match the glibc definitions in <arch-syscall.h>.
      26  
      27     Most architectures do not need these fixups, so the default header
      28     is empty.  */
