'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.

Andrew Morton reported a number of false positives for ia64 - like these:
WARNING: drivers/acpi/button.o - Section mismatch: reference to .init.text: from .IA_64.unwind.init.text after '' (at offset 0x0)
WARNING: drivers/acpi/button.o - Section mismatch: reference to .exit.text: from .IA_64.unwind.exit.text after '' (at offset 0x0)
WARNING: drivers/acpi/processor.o - Section mismatch: reference to .init.text: from .IA_64.unwind after '' (at offset 0x1e8)

They are all false positives - or at least the .c code looks OK.
It is not known why sometimes a section name is appended and sometimes not.

Fix is to accept references from all sections that includes "unwind." in the name.

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
permissions or suddenly became a regular file.
The main reason was that /dev/null was used as output
to gcc in the check-lxdialog.sh script and gcc did
some strange things with the output file; in this
case /dev/null when it errorred out.

Following patch implements a suggestion
from Bryan O'Sullivan <bos@serpentine.com> to
use gcc -print-file-name=libxxx.so.

Also the Makefile is adjusted to not resolve value of
HOST_EXTRACFLAGS and HOST_LOADLIBES until they are actually used.
This prevents us from calling gcc when running make *clean/mrproper

For our future {in}sanity, add a comment that this is the ppc .opd

Any idea why ppc .opd points to discarded sections when ia64 does not?

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).
'make kernelrelease' doesn't care.

Here's the patch for modalias support for input classes.  It uses
comma-separated numbers, and doesn't describe all the potential keys (no
module currently cares, and that would make the strings huge).  The
changes to input.h are to move the definitions needed by file2alias
outside __KERNEL__.  I chose not to move those definitions to
mod_devicetable.h, because there are so many that it might break compile
of something else in the kernel.

The rest is fairly straightforward.
