David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
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.

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.
