Currently it is impossible to edit the value of a config symbol with a
prompt longer than (terminal width - 2) characters. dialog_inputbox()
calculates a negative x-offset for the input window and newwin() fails
as this is invalid. It also doesn't check for this failure, so it
busy-loops calling wgetch(NULL) which immediately returns -1.
The additions in the offset calculations also don't match the intended
size of the window.
Limit the window size and calculate the offset similarly to
show_scroll_win().

The "imply" keyword is a weak version of "select" where the target
config symbol can still be turned off, avoiding those pitfalls that come
with the "select" keyword.
This is useful e.g. with multiple drivers that want to indicate their
ability to hook into a secondary subsystem while allowing the user to
configure that subsystem out without also having to unset these drivers.
Currently, the same effect can almost be achieved with:
config DRIVER_A
tristate
config DRIVER_B
tristate
config DRIVER_C
tristate
config DRIVER_D
tristate
[...]
config SUBSYSTEM_X
tristate
default DRIVER_A || DRIVER_B || DRIVER_C || DRIVER_D || [...]
This is unwieldy to maintain especially with a large number of drivers.
Furthermore, there is no easy way to restrict the choice for SUBSYSTEM_X
to y or n, excluding m, when some drivers are built-in. The "select"
keyword allows for excluding m, but it excludes n as well. Hence
this "imply" keyword. The above becomes:
config DRIVER_A
tristate
imply SUBSYSTEM_X
config DRIVER_B
tristate
imply SUBSYSTEM_X
[...]
config SUBSYSTEM_X
tristate
This is much cleaner, and way more flexible than "select". SUBSYSTEM_X
can still be configured out, and it can be set as a module when none of
the drivers are configured in or all of them are modular.

Pull kconfig update from Michal Marek:
- fix for behavior of tristate choice items and fix for documentation
of existing kconfig behavior [Dirk Gouders]
- more helpful "unexpected data" kconfig warning [Paul Bolle]
* 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
kconfig/symbol.c: handle choice_values that depend on 'm' symbols
kconfig-language: elaborate on the type of a choice
kconfig-language: fix comment on dependency-generated menu structures.
kconfig: add unexpected data itself to warning
If choices consist of choice_values of type tristate that depend on
symbols set to 'm', those choice_values are not set to 'n' if the
choice is changed from 'm' to 'y' (in which case only one active
choice_value is allowed). Those values are also written to the config
file causing modules to be built when they should not.
The following config can be used to reproduce and examine the problem;
with the frontend of your choice set "Choice 0" and "Choice 1" to 'm',
then set "Tristate Choice" to 'y' and save the configuration:
config modules
boolean modules
default y
option modules
config dependency
tristate "Dependency"
default m
choice
prompt "Tristate Choice"
default choice0
config choice0
tristate "Choice 0"
config choice1
tristate "Choice 1"
depends on dependency
endchoice
This patch sets tristate choice_values' visibility that depend on
symbols set to 'm' to 'n' if the corresponding choice is set to 'y'.
This makes them disappear from the choice list and will also cause the
choice_values' value set to 'n' in sym_calc_value() and as a result
they are written as "not set" to the resulting .config file.

Also recognize standalone "prompt".
Before this patch we incorrectly identified some symbols as not having a
prompt and potentially needing to be selected by something else.
Note that this patch could theoretically change the resulting .config,
causing it to have fewer symbols turned on. However, given the current set
of Kconfig files, this situation does not occur because the symbols newly
added to %prompts are absent from %selects.

Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used
to be equivalent to make allmodconfig; these days it hardwires MODULES to n.
In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is
treated as if it set it to n.
Regression had been introduced by commit cfa98f ("kconfig: do not
override symbols already set"); what happens is that conf_read_simple()
does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and
has conf_set_all_new_symbols() skip modules_sym.
It's pretty easy to fix - simply move that call of sym_calc_value()
into the callers, except for the ones in KCONFIG_ALLCONFIG handling.

The Qt Project recommendation is that there should always be a "qmake"

Unfortunately, some distros do not follow the recommendation, so we

My recent commit d2036f30cf ("scripts/kconfig/Makefile: Allow
KBUILD_DEFCONFIG to be a target"), contained a bug in that when it
checks if KBUILD_DEFCONFIG is a file it forgets to prepend $(srctree) to
the path.
This causes the build to fail when building out of tree (with O=), and
when the value of KBUILD_DEFCONFIG is 'defconfig'. In that case we will
fail to find the 'defconfig' file, because we look in the build
directory not $(srctree), and so we will call Make again with
'defconfig' as the target. From there we loop infinitely calling 'make
defconfig' again and again.
The fix is simple, we need to look for the file under $(srctree).

direct use of the script without -m, which called make rules
