Message:

The main modif is in TTY driver: The hard lock implemented in the
vci_multi_tty component is not used anymore, because this (non cacheable)
lock was not scalable... It has been replaced by a software (cacheable) lock
that has a better scalability in case of hardware cache coherence.
(see the _tty_get_lock() and _tty_release_lock() functions)
