Subject: kbuild: obj-dirs is calculated incorrectly if hostprogs-y is defined

When Makefile.host is included, $(obj-dirs) is subjected to the
addprefix operation for the second time.  Prefix only needs to be added
to the newly added directories, but not to those that came from
Makefile.lib.

This causes the build system to create unneeded empty directories in the
build tree when building in a separate directory.  For instance,
lib/lib/zlib_inflate is created in the build tree.

Subject: kbuild: fix make rpm for powerpc

The default target for most powerpc platforms is zImage.  The
zImage however is in arch/powerpc/boot and the mkspec script
was set up to get the kernel from the top level of the kernel
tree.  This patch copies vmlinux to arch/powerpc/boot and then
copies the kernel to the tmp directory so the rpm can be made.

Subject: kconfig: improve config load/save output

During loading special case the first common case (.config), be silent about
it and otherwise mark it as a change that requires saving.  Instead output
that the file has been changed.  IOW if conf does nothing (special), it's
silent.

Subject: kconfig: fix .config dependencies

This fixes one of the worst kbuild warts left - the broken dependencies used
to check and regenerate the .config file.  This was done via an indirect
dependency and the .config itself had an empty command, which can cause make
not to reread the changed .config file.

Instead of this we generate now a new file include/config/auto.conf from
.config, which is used for kbuild and has the proper dependencies.  It's also
the main make target now for all files generated during this step (and thus
replaces include/linux/autoconf.h).

This also means we can now relax the syntax requirements for the .config file
and we don't have to rewrite it all the time, i.e.  silentoldconfig only
writes .config now when it's necessary to keep it in sync with the Kconfig
files and even this can be suppressed by setting the environment variable
KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

From 2e3646e51b2d6415549b310655df63e7e0d7a080 Mon Sep 17 00:00:00 2001
From: Roman Zippel <zippel@linux-m68k.org>
Date: Thu, 8 Jun 2006 22:12:42 -0700
Subject: kconfig: integrate split config into silentoldconfig

Now that kconfig can load multiple configurations, it becomes simple to
integrate the split config step, by simply comparing the new .config file with
the old auto.conf (and then saving the new auto.conf).  A nice side effect is
that this saves a bit of disk space and cache, as no data needs to be read
from or saved into the splitted config files anymore (e.g.  include/config is
now 648KB instead of 5.2MB).

From f6a88aa86027bdecfc74ef7c6bf6c68233e86bb3 Mon Sep 17 00:00:00 2001
From: Roman Zippel <zippel@linux-m68k.org>
Date: Thu, 8 Jun 2006 22:12:44 -0700
Subject: kconfig: add symbol option config syntax

This adds the general framework to the parser to define options for config
symbols with a syntax like:

config FOO
	option bar[="arg"]

From face4374e288372fba67c865eb0c92337f50d5a4 Mon Sep 17 00:00:00 2001
From: Roman Zippel <zippel@linux-m68k.org>
Date: Thu, 8 Jun 2006 22:12:45 -0700
Subject: kconfig: add defconfig_list/module option

This makes it possible to change two options which were hardcoded sofar.
1. Any symbol can now take the role of CONFIG_MODULES
2. The more useful option is to change the list of default file names,
   which kconfig uses to load the base configuration if .config isn't
   available.

From 43bf612af2d4f2615dcbf86af8206e2f40231237 Mon Sep 17 00:00:00 2001
From: Roman Zippel <zippel@linux-m68k.org>
Date: Thu, 8 Jun 2006 22:12:45 -0700
Subject: kconfig: Add search option for xconfig

Implement a simple search request for xconfig.  Currently the capabilities are
rather simple (the same as menuconfig).

From 7fc925fd6a4c24e1db879d227fc0a0f65a335aa1 Mon Sep 17 00:00:00 2001
From: Roman Zippel <zippel@linux-m68k.org>
Date: Thu, 8 Jun 2006 22:12:46 -0700
Subject: kconfig: finer customization via popup menus

This allows to configure every symbol list and info window separately via a
popup menu, these settings are also separately saved and restored.  Cleanup
the ConfigSettings class a bit to reduce the number of #ifdef.

Kconfig does its own indentation of menu prompts, so warn about and ignore
leading whitespace.  Remove also a few unnecessary newlines after other
warning prints.

From b817f6feff4a565b08f0e699a5790b4008b8f494 Mon Sep 17 00:00:00 2001

Subject: kbuild: check license compatibility when building modules

Modules that uses GPL symbols can no longer be build with kbuild,
the build will fail during the modpost step.
When a GPL-incompatible module uses a EXPORT_SYMBOL_GPL_FUTURE symbol
then warn during modpost so author are actually notified.

The actual license compatibility check is shared with the kernel
to make sure it is in sync.

Patch originally from: Andreas Gruenbacher <agruen@suse.de> and
Ram Pai <linuxram@us.ibm.com>

Subject: kbuild: append git revision for all untagged commits

adds revision suffix for untagged commits that are reachable from a tag

I'm bisecting and don't get the -g...... suffix.  The reason is, that

	git name-rev --tags HEAD

returns e.g.

	HEAD tags/v2.6.17-rc1^0~1067

which is currently good enough for setlocalversion to skip the suffix.
This introduces a dependecy to grep -E, which should be fine.

Subject: kbuild: fix make -rR breakage

make failed to supply the filename when using make -rR and using $(*F)
to get target filename without extension.
This bug was not reproduceable in small scale but using:
$(basename $(notdir $@)) fixes it with same functionality.

Subject: kbuild: export-symbol usage report generator

The following patch provides the ability to generate a report of
	(1) All the exported symbols and their in-kernel-module usage count
	(2) For each module, lists the modules and their exported symbols, on
	                  which it depends.

	the report can be generated by executing:
	perl scripts/export_report

The tool warns if the modules are not build using MODVERSIONING.

Subject: kbuild: add option for stripping modules while installing them

Add option for stripping modules while installing them.

This function adds support for stripping modules while they are being
installed.  CONFIG_DEBUG_KERNEL (which will probably become more
popular as developers use kdump) causes the size of the installed
modules to grow by a factor of 9 or so.

Some kernel package systems solve this problem by stripping the debug
information from /lib/modules after running "make modules_install",
but that may not work for people who are installing directly into
/lib/modules --- root partitions that were sized to handle 16 megs
worth of modules may not be quite so happy with 145 megs of modules,
so the "make modules_install" never succeeds.

This patch allows such users to request modules_install to strip the
modules as they are installed.

Subject: kbuild: support for %.symtypes files

Here is a patch that adds a new -T option to genksyms for generating dumps of
the type definition that makes up the symbol version hashes. This allows to
trace modversion changes back to what caused them. The dump format is the
name of the type defined, followed by its definition (which is almost C):

  s#list_head struct list_head { s#list_head * next , * prev ; }

The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef.
The exported symbols do not define types, and thus do not have an x# prefix:

  nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 )

The symbol type defintion of a single file can be generated with:

  make fs/jbd/journal.symtypes

If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that
export symbols are generated.

The single *.symtypes files can be combined into a single file after a kernel
build with a script like the following:

for f in $(find -name '*.symtypes' | sort); do
    f=${f#./}
    echo "/* ${f%.symtypes}.o */"
    cat $f
    echo
done \
| sed -e '\:UNKNOWN:d' \
      -e 's:[,;] }:}:g' \
      -e 's:\([[({]\) :\1:g' \
      -e 's: \([])},;]\):\1:g' \
      -e 's: $::' \
      $f \
| awk '
/^.#/   { if (defined[$1] == $0) {
            print $1
            next
          }
          defined[$1] = $0
        }
        { print }
'

When the kernel ABI changes, diffing individual *.symtype files, or the
combined files, against each other will show which symbol changes caused the
ABI changes. This can save a tremendous amount of time.

Dump the types that make up modversions

Subject: kbuild: replace abort() with exit(1)
