      kbuild: replace abort() with exit(1) · 6803dc0e
      由 Sam Ravnborg 提交于 
      We have had no use of the coredump file for a long time.
So just exit(1) and avoid coredumping.

      kbuild: support for %.symtypes files · 15fde675
      由 Andreas Gruenbacher 提交于 
      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.

      kbuild: fix silentoldconfig recursion · 3041e47e
      由 Roman Zippel 提交于 
      kconfig-fix-config-dependencies causes this:

make CC=cc  KBUILD_VERBOSE=1 -C /usr/src/25 SUBDIRS=/home/akpm/NVIDIA-Linux-x86_64-1.0-8762-pkg2/usr/src/nv modules
make -f /usr/src/devel/Makefile silentoldconfig
make -f /usr/src/devel/Makefile silentoldconfig
make -f /usr/src/devel/Makefile silentoldconfig

The basic problem is if we compile external modules, config-targets isn't
set which can cause recursive calls to silentoldconfig to update the
kernel configuration.

Bail out and ask the user to update manually.

      kbuild: add option for stripping modules while installing them · ac031f26
      由 Theodore Ts'o 提交于 
      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.

      kbuild: export-symbol usage report generator · c5e30033
      由 Ram Pai 提交于 
      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.

      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.
