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.

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.

Change the invocations of make in the output directory Makefile and the
main Makefile for separate object trees to pass all goals to one $(MAKE)
via a new phony target "sub-make" and the existing target _all.

When compiling with separate object directories, a separate make is called
in the context of another directory (from the output directory the main
Makefile is called, the Makefile is then restarted with current directory
set to the object tree).  Before this patch, when multiple make command
goals are specified, each target results in a separate make invocation.
With make -j, these invocations may run in parallel, resulting in multiple
commands running in the same directory clobbering each others results.

I did not try to address make -j for mixed dot-config and no-dot-config
targets.  Because the order does matter, a solution was not obvious.
Perhaps a simple check for MAKEFLAGS having -j and refusing to run would
be appropriate.

The assembler for a while now supports -gdwarf to generate source line info
just like the C compiler does.  Source-level assembly debugging sounds like an
oxymoron, but it is handy to be able to see the right source file and read its
comments rather than just the disassembly.  This patch enables -gdwarf for
assembly files when CONFIG_DEBUG_INFO=y and the assembler supports the option.

You can cause a recursion in kbuild/make with the following:

make O=$PWD kernel/time.o
make mrproper

Of course no one would use O=$PWD (that's just the testcase),
but this happened too often:

/ws/linux/linux-2.6.23$ make O=/ws/linux/linux-2.6.23 kernel/time.o
(Oops - should have been O=/ws/linux/obj-2.6.23!)

out if output directory and source directory are the same.

Recently the __extension__ keyword has been introduced in the kernel.
Teach genksyms about this keyword so it can generate correct CRC for

Later we may add more variants as needed.

Currently scripts/ver_linux prints "Binutils" or other random
information for the version number in the "binutils" output line
on some distributions. This patch corrects that.

When I initially submitted a patch to correct that, I was not aware
that the output from "ld -v" could differ as much as it turned out
it can, so my original fix turned out to not cover all bases.
This patch works correctly with all the different "ld -v" output
that people posted in replys to my first patch, so it should be a
clear win over what we have currently.

To avoid having to look manually for used but undefined Kconfig variables,
I've written a script which tries do this efficiently, in case all other
attention fail.  It accounts for _MODULE suffix and for UML_ prefixes to
Kconfig variable, but otherwise looks for exact matches (i.e.  \<CONFIG_;
this is done to exclude macros like MMCONFIG_).

Undefined Kconfig variables should be not be removed without care, but for
instance arch/i386/boot/ uses a bunch of undefined Kconfig vars:

$ scripts/checkunknowndefines.sh arch/i386/boot/
arch/i386/boot/video.h uses undefined symbol VIDEO_400_HACK
arch/i386/boot/video-vga.c uses undefined symbol VIDEO_400_HACK
arch/i386/boot/video.c uses undefined symbol VIDEO_RETAIN
arch/i386/boot/video.h uses undefined symbol VIDEO_RETAIN
arch/i386/boot/video.h uses undefined symbol VIDEO_SVGA
arch/i386/boot/video.h uses undefined symbol VIDEO_VESA
