  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.  */
