Building an allmodconfig kernel for ppc64 revealed a number of false
positives - originally reported by Andrew Morton.
This patch removes most if not all false positives for ppc64:
Section .opd
The .opd section contains function descriptors at least for ppc64.
So ignore it for .init.text (was ignored for .exit.text).
See description of function descriptors here:
http://www.linuxbase.org/spec/ELF/ppc64/PPC-elf64abi-1.7.html
Section .toc1
ppc64 places some static variables in .toc1 - ignore the.
Section __bug_tabe
BUG() and friends uses __bug_table. Ignore warnings from that section.
Module parameters are placed in .data.rel for ppc64, for adjust pattern to
match on section named .data*
Tested with gcc: 3.4.0 and binutils 2.15.90.0.3

'allnoconfig' is described by 'make help' as a "minimal config", that's not
strictly correct. To be pedantic, a minimal config would be one where
EMBEDDED was set to Y and most things therein disabled etc. Simply
answering 'no' to all options does not give a minimal config.
A better description of allnoconfig is that it answers all options with 'no'.
This patch updates the description.

With the current way of generating the Makefile in the output directory
for builds outside of the source tree, specifying real targets (rather
than phony ones) doesn't work in an already (partially) built tree, as
the stub Makefile doesn't have any dependency information available.
Thus, all targets where files may actually exist must be listed
explicitly and, due to what I'd call a make misbehavior, directory
targets must then also be special cased.

Section mismatch is identified as references to .init*
sections from non .init sections. And likewise references
to .exit.* sections outside .exit sections.
.init.* sections are discarded after a module is initialized
and references to .init.* sections are oops candidates.
.exit.* sections are discarded when a module is built-in and
thus references to .exit are also oops candidates.
The checks were possible to do using 'make buildcheck' which
called the two perl scripts: reference_discarded.pl and
reference_init.pl. This patch just moves the same functionality
inside modpost and the scripts are then obsoleted.
They will though be kept for a while so users can do double
checks - but note that some .o files are skipped by the perl scripts
so result is not 1:1.
All credit for the concept goes to Keith Owens who implemented
the original perl scrips - this patch just moves it to modpost.
Compared to the perl script the implmentation in modpost will be run
for each kernel build - thus catching the error much sooner, but
the downside is that the individual .o file are not always identified.

While running "make menuconfig" and "make mrproper"
some people experienced that /dev/null suddenly changed

case /dev/null when it errorred out.
Following patch implements a suggestion

Currently scripts/setlocalversion is a Perl script that tries to figure
out the current git commit ID of a repo without using git. It also
imports Digest::MD5 without using it and generally is too big for the
small task it does. :] And it always reports a git ID, even when the
HEAD is tagged -- this is a bug.
This patch replaces it with a Bourne Shell script that uses git
commands to do the same. I can't come up with a scenario where someone
would use a git repo and refuse to install git core at the same time,
so I think it's reasonable to assume git is available.
The new script also reports uncommitted changes by adding -git_dirty to
the version string. Obviously you can't see from that _what_ has been
changed from the last commit, so it's more of a reminder that you
forgot to commit something.
The script is easily extensible: simply add a check for Mercurial (or
whatever) below the git check.
Note: the script doesn't print a newline char anymore. That's only
because it was easier to implement it that way, not a feature (or bug).

This is a one-line change to parse.y.
To take advantage of this the scripts/genksyms/*_shipped files needs to
be rebuild - this is the next patch.
When a .c file contains:
DEFINE_PER_CPU(struct foo_s *, bar);
the .cpp output looks like:
__attribute__((__section__(".data.percpu"))) __typeof__(struct foo_s *) per_cpu__bar;
With the existing parse.y, the value inside the paranthesis of
__typeof__() does not evaluate as a type_specifier and therefore
per_cpu__bar does not get assigned a type for genksyms which results in
the EXPORT_PER_CPU_SYMBOL() not generating a CRC value.

patch and for ia64's defconfig, the only change is:

This patch fixes a problem when we use well known kernel symbols as module
names.
For example, if module source name is current.c, idle_stack.c or etc.,
we have a bad KBUILD_MODNAME value.
For example, KBUILD_MODNAME will be "get_current()" instead of "current", or
"(init_thread_union.stack)" instead of "idle_task".
The trick is to define a stringify macro on the commandline - named
KBUILD_STR for namespace reasons - and then to stringify the module
name.
There are a few uses of KBUILD_MODNAME throughout the tree but the usage
is for debug and will not be harmed by this change so left untouched for now.
While at it KBUILD_BASENAME was changed too. Any spinlock usage in the
unix module would have created wrong section names without it.
Usage in spinlock.h fixed so it no longer stringify KBUILD_BASENAME.

When doing its recursive dependency check, scripts/kconfig/conf uses the flag
SYMBOL_CHECK_DONE to avoid rechecking a symbol it has already checked.
However, that flag is only set at the top level, so if a symbol is first
encountered as a dependency of another symbol it will be rechecked every time
it is encountered until it's encountered at the top level.
This patch adjusts the flag setting so that each symbol will only be checked
once, regardless of whether it is first encountered at the top level, or while
recursing down from another symbol. On complex configurations, this vastly
speeds up scripts/kconfig/conf. The config in the powerpc merge tree is
particularly bad: this patch reduces the time for 'scripts/kconfig/conf -o
arch/powerpc/Kconfig' by a factor of 40 on a G5. That's even including the
time to print the config, so the speedup in the actual checking is more likely
2 or 3 orders of magnitude.

qt as installed on fedora core (2 and 3) does not work with vanilla
kernel. The linker fails to locate the qt lib:
Actual Results: # make xconfig
HOSTLD scripts/kconfig/qconf
/usr/bin/ld: cannot find -lqt
collect2: ld returned 1 exit status
Than Ngo has provided following fix for the bug.

I made a patch that detects if libintl.h (needed for nls) is present on the
host system and if it's not, it nls support is disabled by providing
dummies for the used nls functions.
This way if there is nls support on the host system the *config targets
will build according to Arnaldo Carvalho de Melo's i18n modifications, else
it just uses the original English messages.
I have also made a bug report at kernel's bugzilla:
http://bugzilla.kernel.org/show_bug.cgi?id=5501
And there is a discussion about this problem in Gentoo's bugzilla:

This still leaves driver and architecture-specific subdirectories alone,
but gets rid of the bulk of the "generic" generated files that we should
ignore.

- Added a missing TO_NATIVE call to scripts/mod/file2alias.c:do_pcmcia_entry()
- Add an alignment attribute to struct pcmcia_device_no to solve an alignment
issue seen when cross-compiling on x86 for m68k.

Instead of playing all of these hand-coded assembler aliasing games,
just translate symbol names in the name space ".sym" to "_Sym" at
module load time.

$(foo) is an absolute path.

GCC 4 emits more DWARF debugging information than before and there is now a
.debug_loc section as well. This causes "make buildcheck" to fail. Rather
than just add that one to the special case list, I used a regexp to ignore
any .debug_ANYTHING sections in case more show up in the future.

This patch changes the way the compression algorithm works. The base
algorithm is similiar to the previous but we force the compressed token
size to 2.
Having a fixed size compressed token allows for a lot of optimizations, and
that in turn allows this code to run over *all* the symbols faster than it
did before over just a subset.
Having it work over all the symbols will make it behave better when symbols
change positions between passes, and the "inconsistent kallsyms" messages
should become less frequent.
In my tests the compression ratio was degraded by about 0.5%, but the
results will depend greatly on the number of symbols to compress.
