  • We need a location for generated files.
    Today they are spread over several places and bringing them
    together to a common place makes it obvious hat is generated
    and what isreal files.

    Al Viro originally suggested: include/gen
    Linus suggested to spell it out.

    This patch implement support for

    include/generated

    All files in include/generated are ignored by git.
    include/generated is removed during "make mrproper".

    With this we are ready to implement support for include/generated
    in the various architctures and in the base kernel.

  • Linus Torvalds
     
  • With a sufficiently new compiler and binutils, code which wasn't
    previously generating .eh_frame sections has begun to. Certain
    architectures (powerpc, in this case) may generate unexpected relocation
    formats in response to this, preventing modules from loading.

    While the new relocation types should probably be handled, revert to the
    previous behaviour with regards to generation of .eh_frame sections.

    (This was reported against Fedora, which appears to be the only distro
    doing any building against gcc-4.4 at present: RH bz#486545.)

  • Sam Ravnborg says:
    "We have several architectures that plays strange games with $(CC) and
    $(CROSS_COMPILE).

    So we need to postpone any use of $(call cc-option..) until we have
    included the arch specific Makefile so we try with the correct $(CC)
    version."

  • This makes sure that gcc doesn't try to optimize away wrapping
    arithmetic, which the kernel occasionally uses for overflow testing, ie
    things like

    if (ptr + offset < ptr)

    which technically is undefined for non-unsigned types. See

    http://bugzilla.kernel.org/show_bug.cgi?id=12597

    for details.

    Not all versions of gcc support it, so we need to make it conditional
    (it looks like it was introduced in gcc-3.4).

    So the best solution look to remove -r from kernel Makefile

  • Running 'make rpm' fails when CONFIG_LOCALVERSION_AUTO=y and using a kernel source
    tree under SCM. This is due to KERNELRELEASE being different when the initial make
    is run and when make is run from rpmbuild.

    mkspec creates kernel.spec using KERNELRELEASE:

    echo "%files"
    echo '%defattr (-, root, root)'
    echo "%dir /lib/modules"
    echo "/lib/modules/$KERNELRELEASE"
    echo "/lib/firmware"
    echo "/boot/*"
    echo ""

    When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any
    additional version info from SCM. Next, the srctree is tarred up and SCM
    information is excluded.

    rpmbuild reruns make and in the process generates a new include/config/kernel.release
    and thus a new KERNELRELEASE. However this time the SCM information is gone so
    KERNELRELEASE no longer has the additional version information. When "make modules_install"
    runs, it uses the new KERNELRELEASE value to determine where to install the modules.
    This conflicts with where the spec file assumes they are going because of the
    mis-matching KERNELRELEASE versions.

  • It's useful to already have the source symlink in a
    objdir when one just runs make *config. Then one
    can do

    mkdir obj-allyes
    cd obj-allyes
    make -C ../sourcedir O=$(pwd) allyesconfig
    ./source/scripts/config --disable debug_info
    make CC=icecc -j18

    without having to interrupt the make first just to
    get the source symlink.

  • Impact: no default -fno-stack-protector if stackp is enabled, cleanup

    Stackprotector make rules had the following problems.

    * cc support test and warning are scattered across makefile and
    kernel/panic.c.

    * -fno-stack-protector was always added regardless of configuration.

    Update such that cc support test and warning are contained in makefile
    and -fno-stack-protector is added iff stackp is turned off. While at
    it, prepare for 32bit support.

  • 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.
