      [PATCH] headers_check: use a different default directory · 1ab7a1f3
      由 David Woodhouse 提交于 
      `make headers_check' wants to go and write stuff in /lib/modules, which
requires root, whic is unfortunate.

In fact, there's no _particular_ reason for headers_install to put it there
either -- it can go into a subdirectory of the build tree in both cases.
It's not intended to go directly into /usr/include, which is why we didn't
put it there -- and we certainly don't want people screwing around with
symlinking to it.  It's for distributors to take away and do stuff with, so
leaving it in $(objtree) is fine, even in the headers_install case.

I picked $(objtree)/usr/include but I have no _particular_ preference
for that; it just seemed reasonable.

      kbuild: introduce utsrelease.h · 63104eec
      由 Sam Ravnborg 提交于 
      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.

      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
      由 Sam Ravnborg 提交于 
      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
      由 Masatake YAMATO 提交于 
      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
      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.

      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
      由 Sam Ravnborg 提交于 
      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.
