  • 49148020b   m68k,m68knommu: merge header files ... Browse Code »

    Merge header files for m68k and m68knommu to the single location:

    arch/m68k/include/asm

    The majority of this patch was the result of the
    script that is included in the changelog below.

    The script was originally written by Arnd Bergman and
    exten by me to cover a few more files.

    When the header files differed the script uses the following:

    The original m68k file is named _mm.h [mm for memory manager]
    The m68knommu file is named _no.h [no for no memory manager]

    The files uses the following include guard:

    This include gaurd works as the m68knommu toolchain set
    the __uClinux__ symbol - so this should work in userspace too.

    Merging the header files for m68k and m68knommu exposes the
    (unexpected?) ABI differences thus it is easier to actually
    identify these and thus to fix them.

    The commit has been build tested with both a m68k and
    a m68knommu toolchain - with success.

    The commit has also been tested with "make headers_check"
    and this patch fixes make headers_check for m68knommu.

    The script used:

    These stripping patches has caused a set of issues:

    lack of support for `--strip-unneeded-symbols' with objcopy 2.15.92.0.2

    I have some scripts which need to map back to the source directory
    from an objdir. This was so far done by parsing the Makefile,
    but the Makefile format changes occasionally and breaks my scripts
    then.

    To make this more reliable add a "source" symlink back.

  • 9bb482476   allow stripping of generated symbols under CONFIG_KALLSYMS_ALL ... Browse Code »

    Building upon parts of the module stripping patch, this patch
    introduces similar stripping for vmlinux when CONFIG_KALLSYMS_ALL=y.
    Using CONFIG_KALLSYMS_STRIP_GENERATED reduces the overhead of
    CONFIG_KALLSYMS_ALL from 245k/310k to 65k/80k for the (i386/x86-64)
    kernels I tested with.

    The patch also does away with the need to special case the kallsyms-
    internal symbols by making them available even in the first linking
    stage.

    While it is a generated file, the patch includes the changes to
    scripts/genksyms/keywords.c_shipped, as I'm unsure what the procedure
    here is.

  • ad7a953c5   kbuild: strip generated symbols from *.ko ... Browse Code »

    This patch changes the way __crc_ symbols are being resolved from
    using ld to do so to using the assembler, thus allowing these symbols
    to be marked local (the linker creates then as global ones) and hence
    allow stripping (for modules) or ignoring (for vmlinux) them. While at
    this, also strip other generated symbols during module installation.

    One potentially debatable point is the handling of the flags passeed
    to gcc when translating the intermediate assembly file into an object:
    passing $(c_flags) unchanged doesn't work as gcc passes --gdwarf2 to
    gas whenever is sees any -g* option, even for -g0, and despite the
    fact that the compiler would have already produced all necessary debug
    info in the C->assembly translation phase. I took the approach of just
    filtering out all -g* options, but an alternative to such negative
    filtering might be to have a positive filter which might, in the ideal
    case allow just all the -Wa,* options to pass through.

    "Paul Smith" reported that we would fail
    to build with a new check that may be enabled in an
    upcoming version of make.

    The error was:

    Makefile:442: *** mixed implicit and normal rules. Stop.

    The problem is that we did stuff like this:

    config %config: ...

    The solution was simple - the above was split into two with identical
    prerequisites and commands.
    With only three lines it was not worth to try to avoid the duplication.

  • 5e5387900   sparc,sparc64: unify Makefile ... Browse Code »

    To unify Makefile for sparc and sparc64 a few other steps was needed:
    1) separate defconfig files for sparc and sparc64 is required,
    so locate these in arch/sparc/configs
    2) removoval of hack in toplevel Makefile to deal with that
    headers was in a separate directory compared to the rest

    The unification of the Makefile required usage of several

    foo-$(CONFIG_SPARCnn) +=

    due to a few directories pending unification.
    This will be cleaned up when we unify the remaining directories.

    Included in this patch are the deletion of a few files in
    sparc64 as they are no longer needed: Makefile + Kconfig.
    arch/sparc64/ will after this patch is applied only
    have four directories (prom, lib, kernel, boot)

  • a680eedc6   tags and cscope support really belongs in a shell script ... Browse Code »

    as they do not benefit from the make functionality.

    Moving the support to a shell script has several benefits:
    - The readability of the code has increased a lot
    - More people is able to extend the tags support
    - We see less changes to the top-level Makefile

    The shell script version includes improvements from:
    Alexey Dobriyan (jump to kconfig symbols)
    Alexey Dobriyan (drop ./ in paths)
    Ian Campbell (simplified find algorithms)

    This version has a few caveats:
    => It does not support ALLSOURCE_ARCHS
    - it is easy to add if it is really used
    => It assumes all archs have moved to arch/$ARCH/include
    - until that happens we have a few additional hits in the archs

    kbuild failed to expand include flags in KBUILD_CPPFLAGS
    resulting in code like this in arch Makefiles:

    ifeq ($(KBUILD_SRC),)
    KBUILD_CPPFLAGS += -Iinclude/foo
    else
    KBUILD_CPPFLAGS += -I$(srctree)/include/foo

    Move use of LINUXINCLUDE into Makefile.lib to allow
    us to expand -I directives of KBUILD_CPPFLAGS so
    we can avoid the above code.

  • de2addf59   kbuild: do not include arch/<ARCH>/include/asm in find-sources twice. ... Browse Code »

    Architectures which have moved their includes to arch//include
    now list the headers twice in the source listing used by "make
    cscope" and friends, causing those tools to list symbols twice.

    Skipping these files in the ALLSOURCE_ARCHS pass rather than removing
    the ALLINCLUDE_ARCHS pass preserves the semantics of the later.

    o if include/asm is a directory error out

    This fixes a situation where one could be left with a symlink

    would error out.

    include/asm may be a directory if the kernel tree has been copied
