603d49885e kconfig: ignore select of unknown symbol
We have had warnings for a long time about select of unknow symbol
but the warnings does not really makes sense since we may
select a symbol that is relevant and defined in one
arch but not in another arch.
And as long as we do not use a common set of Kconfig files
for all archs lets just ignore this case.

Previously we have used this to find bad uses of
select but we need a more relaible method to do so.

36ef805bd5 kconfig: mark config as changed when loading an alternate config
Michal Zachar <mgzachar@mail.t-com.sk> reported that
menuconfig did not save the new config when loading
an alternate config unless he altered it manually.

Mark config as changed upon load of alternate config fixed this.

f5eaa323eb kconfig: tristate choices with mixed tristate and boolean values
Change kconfig behavior so that mixing bool and tristate config
settings in a choice is possible and has the desired effect of offering
just the tristate options individually if the choice gets set to M, and
a normal boolean selection if the choice gets set to Y.

Also fix scripts/kconfig/conf's handling of children of choice values -
there may be more than one immediate child, and all of them need to be
processed.

09af091f50 kconfig: make kconfig MinGW friendly
Kconfig is powerfull tool. So powerfull that more and more software
projects are using it for configuration. So instead of fixing some of
them one by one, lets fix it in kernel and wait for sync.

This work was originaly done for PTXdist - GPL licensed build system for
userlands and cross-compilers, but it will not hurt kernel kconfig
either. PTXdist menuconfig now works on Windows linked with PDCurses and
compiled using MinGW - there is no termios and signals.

* Do not include <sys/wait.h> and <signal.h> (comes from times when
  lxdialog was separate process)
* Do not mess with termios directly and let curses tell screen size.
  Comment to commit c8dc68ad0f says
  check for screen size could be removed later, but because it didn't
  happen for more than year I left it here as well.
* Save cursor position added by Sam

2f4b489b77 kconfig: use getopt() in conf.c for handling command line arguments
Switch from doing our own parsing of command line arguments to
using getopt(3) to do it.  Aside from simplifying things, this allows us to
specify multiple arguments; the old code could only accept two arguments
(input_mode and kconfig name).

Note some subtle changes:
 - The argument '-?' is no longer supported.
 - '-h' is not treated as an error, so output goes to stdout, and we
   exit with '0'.
 - There is no compatibility checking amongst arguments; the last option
   will simply override earlier options.  For example, 'conf -n -y foo'
   is perfectly valid now (input_mode will be set_yes).  Previously, that
   would have been an error ("can't find file -y").

6840999b19 x86: simplify "make ARCH=x86" and fix kconfig all.config
Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in
all.config.

For a fix the diffstat is nice:
 6 files changed, 3 insertions(+), 36 deletions(-)

The patch reverts these commits:
 - 0f855aa64b ("kconfig: add helper to set
   config symbol from environment variable")
 - 2a113281f5 ("kconfig: use $K64BIT to
   set 64BIT with all*config targets")

Roman Zippel pointed out that kconfig supported string compares so
the additional complexity introduced by the above two patches were
not needed.

With this patch we have following behaviour:

  # make {allno,allyes,allmod,rand}config [ARCH=...]
  option \ host arch      | 32bit         | 64bit
  =====================================================
  ./.                     | 32bit         | 64bit
  ARCH=x86                | 32bit         | 32bit
  ARCH=i386               | 32bit         | 32bit
  ARCH=x86_64             | 64bit         | 64bit

The general rule are that ARCH= and native architecture takes
precedence over the configuration.

So make ARCH=i386 [whatever] will always build a 32-bit kernel
no matter what the configuration says.  The configuration will
be updated to 32-bit if it was configured to 64-bit and the
other way around.

This behaviour is consistent with previous behaviour so no
suprises here.

make ARCH=x86 will per default result in a 32-bit kernel but as
the only ARCH= value x86 allow the user to select between 32-bit
and 64-bit using menuconfig.

daa93fab82 x86: enable "make ARCH=x86"
After unification of the Kconfig files and
introducing K64BIT support in kconfig
it required only trivial changes to enable
"make ARCH=x86".

With this patch you can build for x86_64 in several ways:
1) make ARCH=x86_64
2) make ARCH=x86 K64BIT=y
3) make ARCH=x86 menuconfig
   => select 64-bit

Likewise for i386 with the addition that
i386 is default is you say ARCH=x86.

2a113281f5 kconfig: use $K64BIT to set 64BIT with all*config targets
The variable K64BIT can now be used to select the
value of CONFIG_64BIT.

This is for example useful for powerpc to generate
allmodconfig for both bit sizes - like this:
make ARCH=powerpc K64BIT=y
make ARCH=powerpc K64BIT=n

To use this the Kconfig file must use "64BIT" as the
config value to select between 32 and 64 bit.

e8b8c97773 Revert "kconfig: tristate choices with mixed tristate and boolean values"
This reverts commit a5bf3d891a.

David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:

  "That Kconfig hasn't changed (other than adding new drivers), and it's
   worked that way for several years now ...  so the issue seems to be
   changes in menuconfig/kconfig/etc semantics.

   The issue is that when USB_GADGET=m, it's no longer possible to
   configure peripheral controller drivers as modules ...  the
   controller drivers can now only be configured for static linkage.

   It should be making a choice of one of the controller drivers which
   could work on the target system, and allow that driver to be linked
   either as a module (ok iff USB_GADGET=m) or statically."

Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.

b5d609dbfa kconfig/menuconfig: distinguish between selected-by-another options and comments
menuconfig currently represents options implied by another option ('select'
directive in Kconfig) by prefixing them with '---'.  Unfortunately the same
notation is used for comments.  If the implied option is module capable,
user can still switch between Y and M, all without any feedback until she
visits option's help.  (try saying M to MAC80211 and then toggling
CFG80211)

This patch changes notation of selected-by-another items by introducing 2
new representations for implied options: {*} or {M} for options selected by
another modularized one, thus builtin or module capable, -*- or -M- for
options that cannot be at the moment changed by user.

The idea is to represent actual capability of the option by braces (dashes)
around and to always report actual state by * or M inside.

aa1e5ef5c1 kbuild: check if we can link gettext not just compile
cygwin provides the header file but the lib file needs
to be added manually. A generic fix is to check if
we can compile and link a program that uses gettext()
and if it fails fall back to NO_NLS.

International users of cygwin may have to specify
HOST_LOADLIBES := "-lintl" on the make command line.

f82f3f9422 kconfig: oldconfig shall not set symbols if it does not need to
Avoid setting the value if the symbol doesn't need to be changed or can't
be changed. Later choices may change the dependencies and thus the
possible input range.

make oldconfig from a 2.6.22 .config with CONFIG_HOTPLUG_CPU not set
was in some configurations setting CONFIG_HOTPLUG_CPU=y without asking,
even when there was no actual requirement for CONFIG_HOTPLUG_CPU.
This was triggered by SUSPEND_SMP that does a select HOTPLUG_CPU.

This patch does this and at the same time introduce a few API
funtions used to access the help text.

The relevant api functions are introduced in the various frontends.

d8982ba1f2 kconfig: reset generated values only if Kconfig and .config agree.
Normally generated values (Kconfig entries without a prompt) are cleared as
they are regenerated anyway and so they appear as new should they become
visible and defaults work as expected (once a value is set defaults aren't
used anymore).

The detection whether a value is generated or not is only based on its
visibility status, which can quickly change for a lot of symbols by just
removing a single line from .config or adding a dependency to Kconfig as you
noticed.

The patch now suppresses this logic when .config and Kconfig aren't in sync
and .config needs to be updated, so that you can remove now a random value
from .config and oldconfig won't reask for many other values.

0584f9f9cb kconfig: strip 'CONFIG_' automatically in kernel configuration search
Modify the ncurses configuration tool ('make menuconfig') in a way that the
user can enter the search string (/) both with or without the leading
'CONFIG_'.

This simplifies using copy & paste from .config files because you can
select the whole word.

b70e325cfe kconfig: fix update-po-config
Massimo Maiurana <maiurana@gmail.com> reported that
update-po-config was broken:
1) spelling errors in Makefile so arch/um failed
2) UTF-8 was not supported

The following patch address the above problems.
kxgettext now append the output to the .pot file
generated by xgettext - so we have a header.
In all places UFT-8 is specifed so we now flawlessly
support UTF-8.
The Kconfig files had an empty string in a few cases -
these are now supressed in kxgettext.

With this the translators can now pick up where they left
and get it all translated.
There are ~11000 strings to be translated...
