  • 22c1587ad   init: delete the __cpuinit related stubs ... Browse Code »

    The __cpuinit support was removed several releases ago in 3.11-rc1 with
    commit 22f0a27367742f65130c0fb25ef00f7297e032c1 ("init.h: remove __cpuinit
    sections from the kernel")

    People have had a chance to update their out of tree code, so now we remove
    the no-op stubs to ensure no more new use cases can creep back in.

    Also delete the mention of __cpuinitdata from the tag script.

    The emacs --regex for DEFINE_HASHTABLE produced a warning because of
    an unmatched '\('. Further, the whole entry did not work, because the
    regex needs to match from the beginning of a line, including keywords
    like 'static'. Finally, '\w' should not be used, because it
    stops at underscores which are often part of variable names in C,
    resulting in wrong entries in the tags file.

  • 9b24a15d8   scripts/tags.sh: ignore symlink'ed source files ... Browse Code »

    Since commit 22d651dcef536c75f75537290bf3da5038e68b6b ('selftests/powerpc:
    Import Anton's memcpy / copy_tofrom_user tests'), some source files in the
    tree appear as symlink.
    Until commit 8c38a5328af8080bc69a25b3e4e144b03eeea95e ('scripts/tags.sh:
    ignore code of user space tools'), those symlinks made cscope report some
    warnings:

    $ make ALLSOURCE_ARCHS=all O=./obj-cscope/ cscope
    GEN cscope
    cscope: cannot find
    file .../tools/testing/selftests/powerpc/copyloops/copyuser_power7.S
    cscope: cannot find
    file .../tools/testing/selftests/powerpc/copyloops/memcpy_64.S
    cscope: cannot find
    file .../tools/testing/selftests/powerpc/copyloops/memcpy_power7.S
    cscope: cannot find
    file .../tools/testing/selftests/powerpc/copyloops/copyuser_64.S

    In order to prevent the same kind of warnings to be triggered by future
    addition of symlinks, the best option is to ignore all symlinks when
    building the file list to be processed by cscope (and other tools
    supported by scripts/tags.sh).

    Ignoring symlinks won't hide source files from cscope (and others) as the
    target of these symlinks already appear somewhere else in the tree, and,
    as such, should be processed by cscope (or others).

    Note that, cscope, when used with -R option to make it find the files to
    process by itself, already skip symlinks: it's not expected that cscope
    access source files through symlink.

    On top of commit 8c38a5328af8080bc69a25b3e4e144b03eeea95e ('scripts/tags.sh:
    ignore code of user space tools'), scripts/tags.sh output from
    "make cscope tags TAGS" is the same with and without this patch: it doesn't
    seems to introduce any regression (on Fedora 20).

  • 79c704a87   scripts/tags.sh: add regular expression replacement pattern for memcg ... Browse Code »

    Currently, while using ctags to read code, we would get stumbled on
    PageCgroup* symbols: no definition found. And it is quite dull to
    manually dig it out.

    This patch adds regular expression replacement pattern for such symbols,
    like what have done for the PageXXX flag. It will teach ctags to find
    out the definition for us.

  • ae63b2d7b   scripts/tags.sh: Ignore *.mod.c ... Browse Code »

    CONFIG_MODVERSIONS=y results in a .mod.c for every compiled file in the
    kernel. Issuing a 'make cscope' on a compiled kernel tree results in
    the cscope files containing *.mod.c files.

    [prarit@prarit linux]# make cscope
    [prarit@prarit linux]# cat cscope.files | grep mod.c | wc -l
    4807

    These files are not useful for cscope and should be ignored. For example,

    # line filename / context / line
    1 105 arch/x86/kvm/kvm-intel.mod.c <>
    { 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) },
    2 508 drivers/block/mtip32xx/mtip32xx.h <>
    int numa_node;
    3 55 drivers/block/mtip32xx/mtip32xx.mod.c <>
    { 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) },
    4 37 drivers/cpufreq/acpi-cpufreq.mod.c <>
    { 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) },

    Add an export to RCS_FIND_IGNORE so it can be used in scripts/tags.sh
    and add explicitly ignore *.mod.c files.

    This is almost (but not quite) PowerPC specific and this change should

    Given that absolute paths can be forced by make O=. cscope, change the
