- * linux/drivers/char/keyboard.c
- *
- * Keyboard driver for Linux v0.99 using Latin-1.
- *
- * Written for linux by Johan Myreen as a translation from
- * the assembly version by Linus (with diacriticals added)
- *
- * Some additional features added by Christoph Niemann (ChN), March 1993
- *
- * Loadable keymaps by Risto Kankkunen, May 1993
- *
- * Diacriticals redone & other small changes, aeb@cwi.nl, June 1993
- * Added decr/incr_console, dynamic keymaps, Unicode support,
- * dynamic function/string keys, led setting,  Sept 1994
- * `Sticky' modifier keys, 951006.
