    personalities.
  * Fixed decoding of SG_* and LOOP_* ioctl commands.

  * Implemented decoding of DM_* ioctl commands.
  * Implemented decoding of attr parameter of perf_event_open syscall.
  * Implemented decoding of pkey_alloc, pkey_free, and pkey_mprotect syscalls.
  * Implemented dumping of mq_timedsend and mq_timedreceive syscalls.
  * Implemented decoding of PR_SET_FP_MODE and PR_GET_FP_MODE operations
    of prctl syscall.
  * Implemented PTRACE_GETREGS API support on m68k.
  * Updated lists of ARCH_*, BPF_*, BTRFS_*, FALLOC_*, MS_*, *_MAGIC,
    and V4L2_* constants.
  * Updated lists of ioctl commands from Linux 4.9.
  * Added decoding of recently added syscalls on arc, x32, and xtensa.
  * Enhanced manual page.

* Bug fixes
  * Fixed corner cases in decoding of exit, exit_group, futimesat, getgroups,
    getresuid, init_module, inotify_init1, kcmp, kexec_load, lookup_dcookie,
    mq_getsetattr, mq_notify, mq_open, mq_timedreceive, mq_timedsend,
    name_to_handle_at, prctl, process_vm_readv, process_vm_writev, setfsuid,
    setgroups, setns, unshare, and utimes syscalls.
  * Fixed handling of verbose flag in printing of controls array
    of struct v4l2_ext_controls.
  * Fixed omission of field names in the output of capability, sigaction,
    sigevent, statfs, timespec, timeval, and utimbuf structures.
  * Fixed printing of unknown syscalls in siginfo structure.
  * Fixed decoding of ioctl constants on m68k.
  * Fixed cris architecture support.
  * Fixed cross build when host compiler does not support the same
    set of warning flags as the cross compiler.
  * Fixed build on SLE10 and SLE11.
