      kbuild: introduce utsrelease.h · 63104eec
      Sam Ravnborg authored
      include/linux/version.h contained both actual KERNEL version
      and UTS_RELEASE that contains a subset from git SHA1 for when
      kernel was compiled as part of a git repository.
      This had the unfortunate side-effect that all files including version.h
      would be recompiled when some git changes was made due to changes SHA1.
      Split it out so we keep independent parts in separate files.
      
      Also update checkversion.pl script to no longer check for UTS_RELEASE.

      kbuild: documentation change on allowing checkers besides sparse · 701842e3
      Dustin Kirkland authored
      Minor documentation change on allowing checkers besides sparse
      
      This patch cleans up a couple of mentions of sparse in the inline
      toplevel Makefile documentation such that it's clear that other checkers
      besides sparse can override CHECK and CHECKFLAGS.

      kbuild: fix ia64 breakage after introducing make -rR · 5e8d780d
      Sam Ravnborg authored
      kbuild used $¤(*F to get filename of target without extension.
      This was used in several places all over kbuild, but introducing
      make -rR broke his for all cases where we specified full path to
      target/prerequsite. It is assumed that make -rR disables old style
      suffix-rules which is why is suddenly failed.
      
      ia64 was impacted by this change because several div* routines in
      arch/ia64/lib are build using explicit paths and then kbuild failed.
      
      Thanks to David Mosberger-Tang <David.Mosberger@acm.org> for an explanation
      what was the root-cause and for testing on ia64.
      
      This patch also fixes two uses of $(*F) in arch/um

      kbuild: adding symbols in Kconfig and defconfig to TAGS · e838db68
      Masatake YAMATO authored
      I'm using TAGS generated from "make TAGS" to read the kernel source code.
      
      When I met a ifdef block
      
      	  #ifdef CONFIG_FOO
      	  	 ...
      	  #endif
      
      in the soruce code I would like to know the meaning CONFIG_FOO
      to decide whether I should read inside the ifdef block
      or not. meaning CONFIG_FOO is well documented in Kconfig.
      So it is nice if I can jump to CONFIG_FOO entry in Kconfig
      from "#ifdef CONFIG_FOO" with the tag jump.
      
      Here is the patch to add symbols in Kconfig and defconfig to TAGS
      in "make TAGS" operation.

      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: fix silentoldconfig recursion · 3041e47e
      Roman Zippel authored
      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
      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.

      Basic implementation of 'make headers_check' · 68475359
      David Woodhouse authored
      Based on the 'headers_install' target, this performs a basic sanity check
      on the exported headers -- so far only checking that they do not include
      any other headers which aren't selected for import, but easily extendable.

      This adds a make target which exports a subset of headers which contain
      definitions which are useful for system libraries and tools. It uses the
      BSD 'unifdef' tool to remove instances of #ifdef __KERNEL__, and uses
      sed to remove markers like __user.

      kbuild: ignore make's built-in rules & variables · 566f81ca
      Sam Ravnborg authored
      kbuild does explicitly specify what to do in all cases, and each
      time make's built-in rules & variables has been used it has been a bug.
      So to speed up things and to avoid the hard-to-debug error situations
      ignore the built-in definitions.
      If any part of the kernel uses the built-in definitions the build will
      just stop there and it should be trivial to fix.

      [PATCH] x86_64: Don't define string functions to builtin · 6edfba1b
      Andi Kleen authored
      gcc should handle this anyways, and it causes problems when
      sprintf is turned into strcpy by gcc behind our backs and
      the C fallback version of strcpy is actually defining __builtin_strcpy
      
      Then drop -ffreestanding from the main Makefile because it isn't
      needed anymore and implies -fno-builtin, which is wrong now.
      (it was only added for x86-64, so dropping it should be safe)
