      Revert "kbuild: fix make -rR breakage" · d38b6968
      Linus Torvalds authored
      This reverts commit e5c44fd8.
      
      Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem.
      
      Daniel says:
      
        "[The] reason is a recent change that made modules always shows as
         module.mod.  it breaks modprobe and probably many scripts..besides
         lsmod looking horrible
      
         stuff like this in modprobe.conf:
              install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia
         makes modprobe fork/exec endlessly calling itself...until oom
         interrupts it"

      kbuild: replace abort() with exit(1) · 6803dc0e
      Sam Ravnborg authored
      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
      Andreas Gruenbacher authored
      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: add option for stripping modules while installing them · ac031f26
      Theodore Ts'o authored
      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
      Ram Pai authored
      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.

      kbuild: fix make -rR breakage · e5c44fd8
      Sam Ravnborg authored
      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.
