[PATCH 1/1] kconfig: fix lists definition for C++

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

The C++ compiler is more strict in that it refuses to assign
a void* to a struct list_head*.

Fix that by explicitly casting the poisonning constants.

(Tested with all 5 frontends, now.)

Given that the code _isn't_ C++ (because C is not a subset of C++ but a  
separate langauge in its own right where "throw" is a legitimate  
variable name and so on), how is this an issue?

It's an issue because the xconfig frontends is qconf, which as the name
implies is using Qt, which *is* C++, and includes list.h.

So, list.h is included by both by C and C++ code.

So yes, list.h can be compiled by a C++ compiler.

Now, granted: list.h should all be enclosed in:
    ifdef __cpluplus
    extern "C" {
    endif
    ...
    ifdef __cpluplus
    }
    endif

Was that the fix you were suggesting between the lines? ;-)

Yann E. MORIN.

It does more clearly document the issue. (A comment about the QT  
front-end would also be nice. I don't use that one, so I didn't think  
of it.)

[pull request] Pull request for branch yem-kconfig-for-next

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

Hello Michal, All!

These are the patches against kconfig that I have accumulated for 3.11,
and for which I plan to later send a proper pull-request.

Note-whorthy this time:
  - fix values of tristates that are selected by boolean choices (Arve)
  - fix choice randomisation in presence of KCONFIG_ALLCONFIG    (me)
  - fix choice randomisation selecting more than one value in
    a choice (but only if it is conditional)                     (me)
  - fix choice-in-a-choice randomisation not selecting any value
    for the inner-most choice                                    (me)

Also, some code-cleanups and eye-candy:
  - mconf and nconf code cleanups                                (Dirk, Sedat)
  - mconf and nconf eye-candy                                    (Dirk)
  - scripts/config script-name in help text                      (Clément)
  - heuristic to sort found symbols by relevance                 (me)
  - more randconfig debugging help                               (me)

Note: this series is for review before I send an official pull-request.
I want to avoid the debacle [0] [1] of the last kconfig breakage I caused
with my previous kconfig "fix" to randomising choices in presence of
KCONFIG_ALLCONFIG.

I would like to send an official pull-request early next week, so all of
these can land early in -next, so they get some real-life t4esting before
the next merge windows open. So please, please, test this carefully. ;-)

I tested this a bit, it works fine. Unless somebody else finds issues,
I'll merge it.

Could you please wait a few days (say friday, or monday), I know someone
whose supposed to do some testing on his use-case (Hello Thomas! ;-) ).

Michal,

Please pull this to revert:
    422c809: fix randomising choice entries in presence of KCONFIG_ALLCONFIG

It causes more harm that it fixes issues, and I couldn't find a proper
fix for now. To avoid breakage so close to the opening of the merge
window, it makes more sense to revert it than to wait for a fix.

As I already said earlier, I'll be on vacation the next two weeks, so
I should find some time to look back at this again, hopefully before
-rc1 is out (but any sane person that value his/her life should not hold
his/her breath...)
