This is the last and most important step in the input core conversion. 

It removes pc_keyb and keybdev, connecting keyboard.c straight into
the input core. No arch specific keyboard.c code anymore - every
keyboard driver is now expected to be an input driver.

The module will be called busmouse.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_PSMOUSE
The PS/2 mouse connects to a special mouse port that looks much like
the keyboard port (small circular connector with 6 pins). This way,
the mouse does not use any serial ports. This port can also be used
for other input devices like light pens, tablets, keypads. Compaq,
AST and IBM all use this as their mouse port on currently shipping
machines. The trackballs of some laptops are PS/2 mice also. In
particular, the C&T 82C710 mouse on TI Travelmates is a PS/2 mouse.
Although PS/2 mice are not technically bus mice, they are explained
in detail in the Busmouse-HOWTO, available from
<http://www.linuxdoc.org/docs.html#howto>.
When using a PS/2 mouse, you can get problems if you want to use the
mouse both on the Linux console and under X. Using the "-R" option
of the Linux mouse managing program gpm (available from
<ftp://gnu.systemy.it/pub/gpm/>) solves this problem, or you can get
the "mconv2" utility from <ftp://ibiblio.org/pub/Linux/system/mouse/>.
CONFIG_QIC02_TAPE
If you have a non-SCSI tape drive like that, say Y. Or, if you want
to compile this driver as a module ( = code which can be inserted in
