  • The termios and other changes mean the other protections needed on the driver
    tty arrays should be adequate. Turn it all back on.

  • I sent GregKH this after the pre-requisites. He dropped the pre-requesites
    for good reason and unfortunately then applied this patch. Without this
    reverted you get random kernel memory corruption which will make bisecting
    anything between it and the properly applied patches a complete sod.

  • This reverts the tty layer change to use per-tty locking, because it's
    not correct yet, and fixing it will require some more deep surgery.

    The main revert is d29f3ef39be4 ("tty_lock: Localise the lock"), but
    there are several smaller commits that built upon it, they also get
    reverted here. The list of reverted commits is:

    fde86d310886 - tty: add lockdep annotations
    8f6576ad476b - tty: fix ldisc lock inversion trace
    d3ca8b64b97e - pty: Fix lock inversion
    b1d679afd766 - tty: drop the pty lock during hangup
    abcefe5fc357 - tty/amiserial: Add missing argument for tty_unlock()
    fd11b42e3598 - cris: fix missing tty arg in wait_event_interruptible_tty call
    d29f3ef39be4 - tty_lock: Localise the lock

    The revert had a trivial conflict in the 68360serial.c staging driver
    that got removed in the meantime.

  • In each remaining case the tty_lock is associated with a specific tty. This
    means we can now lock on a per tty basis. We do need tty_lock_pair() for
    the pty case. Uglier but still a step in the right direction.

  • We used it really only serial and ami_serial. The rest of the
    callsites were BUG/WARN_ONs to check if BTM is held. Now that we
    pruned tty_locked from both of the real users, we can get rid of
    tty_lock along with __big_tty_mutex_owner.
