The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

Input device configuration
menu "Input device support" depends on !S390
config INPUT tristate "Generic input layer (needed for keyboard, mouse, ...)" if EXPERT default y help Say Y here if you have any input device (mouse, keyboard, tablet, joystick, steering wheel ...) connected to your system and want it to be available to applications. This includes standard PS/2 keyboard and mouse.
Say N here if you have a headless (no monitor, no keyboard) system.
More information is available: <file:Documentation/input/input.txt>
If unsure, say Y.
To compile this driver as a module, choose M here: the
module will be called input.
if INPUT
config INPUT_FF_MEMLESS tristate "Support for memoryless force-feedback devices" help Say Y here if you have memoryless force-feedback input device such as Logitech WingMan Force 3D, ThrustMaster FireStorm Dual Power 2, or similar. You will also need to enable hardware-specific driver.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called ff-memless.
config INPUT_POLLDEV tristate "Polled input device skeleton" help Say Y here if you are using a driver for an input device that periodically polls hardware state. This option is only useful for out-of-tree drivers since in-tree drivers select it automatically.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called input-polldev.
config INPUT_SPARSEKMAP tristate "Sparse keymap support library" help Say Y here if you are using a driver for an input device that uses sparse keymap. This option is only useful for out-of-tree drivers since in-tree drivers select it automatically.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called sparse-keymap.
comment "Userland interfaces"
config INPUT_MOUSEDEV tristate "Mouse interface" if EXPERT default y help Say Y here if you want your mouse to be accessible as char devices 13:32+ - /dev/input/mouseX and 13:63 - /dev/input/mice as an emulated IntelliMouse Explorer PS/2 mouse. That way, all user space programs (including SVGAlib, GPM and X) will be able to use your mouse.
If unsure, say Y.
To compile this driver as a module, choose M here: the
module will be called mousedev.
config INPUT_MOUSEDEV_PSAUX bool "Provide legacy /dev/psaux device" default y depends on INPUT_MOUSEDEV help Say Y here if you want your mouse also be accessible as char device 10:1 - /dev/psaux. The data available through /dev/psaux is exactly the same as the data from /dev/input/mice.
If unsure, say Y.
config INPUT_MOUSEDEV_SCREEN_X int "Horizontal screen resolution" depends on INPUT_MOUSEDEV default "1024" help If you're using a digitizer, or a graphic tablet, and want to use it as a mouse then the mousedev driver needs to know the X window screen resolution you are using to correctly scale the data. If you're not using a digitizer, this value is ignored.
config INPUT_MOUSEDEV_SCREEN_Y int "Vertical screen resolution" depends on INPUT_MOUSEDEV default "768" help If you're using a digitizer, or a graphic tablet, and want to use it as a mouse then the mousedev driver needs to know the X window screen resolution you are using to correctly scale the data. If you're not using a digitizer, this value is ignored.
config INPUT_JOYDEV tristate "Joystick interface" help Say Y here if you want your joystick or gamepad to be accessible as char device 13:0+ - /dev/input/jsX device.
If unsure, say Y.
More information is available: <file:Documentation/input/joystick.txt>
To compile this driver as a module, choose M here: the
module will be called joydev.
config INPUT_EVDEV tristate "Event interface" help Say Y here if you want your input device events be accessible under char device 13:64+ - /dev/input/eventX in a generic way.
To compile this driver as a module, choose M here: the
module will be called evdev.
config INPUT_EVBUG tristate "Event debugging" help Say Y here if you have a problem with the input subsystem and want all events (keypresses, mouse movements), to be output to the system log. While this is useful for debugging, it's also a security threat - your keypresses include your passwords, of course.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called evbug.
config INPUT_APMPOWER tristate "Input Power Event -> APM Bridge" if EXPERT depends on INPUT && APM_EMULATION help Say Y here if you want suspend key events to trigger a user requested suspend through APM. This is useful on embedded systems where such behaviour is desired without userspace interaction. If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called apm-power.
config XEN_KBDDEV_FRONTEND tristate "Xen virtual keyboard and mouse support" depends on XEN_FBDEV_FRONTEND default y select XEN_XENBUS_FRONTEND help This driver implements the front-end of the Xen virtual keyboard and mouse device driver. It communicates with a back-end in another domain.
