Currently, if you call scripts/gcc-version.sh without arguments it will
generate this output :
$ sh scripts/gcc-version.sh
scripts/gcc-version.sh: line 12: [: =: unary operator expected
scripts/gcc-version.sh: line 16: -E: command not found
scripts/gcc-version.sh: line 17: -E: command not found

Not too pretty. I believe this is an improvement :
$ sh scripts/gcc-version.sh

Fix modpost segfault.
Before:
-------

FATAL: section header offset=815726848 in file 'ath_pci.o' is bigger then filesize=153968

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
arch/i386/boot/video-vesa.c uses undefined symbol VIDEO_VESA
It should also be mentioned in SubmittingPatches and SubmitChecklist.

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.

With the net namespaces many code leaved the __init section,
thus making the kernel occupy more memory than it did before.
Since we have a config option that prohibits the namespace
creation, the functions that initialize/finalize some netns
stuff are simply not needed and can be freed after the boot.
Currently, this is almost not noticeable, since few calls
are no longer in __init, but when the namespaces will be
merged it will be possible to free more code. I propose to
use the __net_init, __net_exit and __net_initdata "attributes"
for functions/variables that are not used if the CONFIG_NET_NS
is not set to save more space in memory.
The exiting functions cannot just reside in the __exit section,
as noticed by David, since the init section will have
references on it and the compilation will fail due to modpost
checks. These references can exist, since the init namespace
never dies and the exit callbacks are never called. So I
introduce the __exit_refok attribute just like it is already
done with the __init_refok.

SSB is an SoC bus used in a number of embedded devices. The most
well-known of these devices is probably the Linksys WRT54G, but there
are others as well. The bus is also used internally on the BCM43xx
and BCM44xx devices from Broadcom.
This patch also includes support for SSB ID tables in modules, so
that SSB drivers can be loaded automatically.

This version brings a number of new checks, and a number of bug
fixes. Of note:
- checks for spacing on round and square bracket combinations
- loosening of the single statement brace checks, to allow
them when they contain comments or where other blocks in a
compound statement have them.
- parks the multple declaration support
- allows architecture defines in architecture specific headers
Andy Whitcroft (21):
Version: 0.09
loosen single statement brace checks
fix up multiple declaration to avoid function arguments
add some function space parenthesis check exceptions
handle EXPORT_'s with parentheses in their names
clean up some warnings in multi-line macro bracketing support
park the multiple declaration checks
make block brace checks count comments as a statement
__volatile__ and __extension__ are not functions
allow architecture specific defined within architecture includes
check spacing on square brackets
check spacing on parentheses
ensure we apply checks to the part before start comment
check #ifdef conditional spacing
handle __init_refok and __must_check
add noinline to inline checks
prevent email addresses from tripping spacing checks
handle typed initialiser spacing
handle line contination as end of line
add bool to the type matcher
refine EXPORT_SYMBOL checks to handle pointers

The Xtensa architecture places literal pools in sections separate
from the instructions. The corresponsing text sections, therefore,
reference the .literal section, and we have to suppress those
warnings.
The naming convention defines the name for a literal
section as .SECTION.literal, unless .SECTION is .text. In that case
the name is only .literal. Using strncmp() instead of strcmp()
to compare the from-section with .SECTION.init.refok in pattern 0
should not cause any regressions for other architectures.
We also need to suppress warnings for two informational
sections (.xt.lit and .xt.prop) used by the Xtensa architecture.

In the whitelist function of modpost now use the same
check to identify init_section as in other places of modpost.
This has the effect that we now recognize sections named
.init.text.19 as init sections and we no longer warn
when we see these.
At the same time make surrounding code readable by dropping
use of temporary flags.
