MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move necessary stuff in escc.h and update type names.
Remove slavio_serial_ms_kbd_init().
Fix code style problems reported by checkpatch.pl
Update mac_newworld, mac_oldworld and sun4m to use directly the
QDEV interface.
