  • 28bc24fc4   vc: separate state ... Browse Code »

    There are two copies of some members of struct vc_data. This is because
    we need to save them and restore later. Move these memebers to a
    separate structure called vc_state. So now instead of members like:
    vc_x, vc_y and vc_saved_x, vc_saved_y
    we have
    state and saved_state (of type: struct vc_state)
    containing
    state.x, state.y and saved_state.x, saved_state.y

    This change:
    * makes clear what is saved & restored
    * eases save & restore by using memcpy (see save_cur and restore_cur)

    Finally, we document the newly added struct vc_state using kernel-doc.

  • a7f7f6248   treewide: replace '---help---' in Kconfig files with 'help' ... Browse Code »

    Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
    '---help---'"), the number of '---help---' has been gradually
    decreasing, but there are still more than 2400 instances.

    This commit finishes the conversion. While I touched the lines,
    I also fixed the indentation.

    There are a variety of indentation styles found.

    a) 4 spaces + '---help---'
    b) 7 spaces + '---help---'
    c) 8 spaces + '---help---'
    d) 1 space + 1 tab + '---help---'
    e) 1 tab + '---help---' (correct indentation)
    f) 1 tab + 1 space + '---help---'
    g) 1 tab + 2 spaces + '---help---'

    In order to convert all of them to 1 tab + 'help', I ran the
    following commend:

    $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

    We don't call braille_register_console() without CON_BRL flag set.
    And the _braille_unregister_console() already tests for console to have
    CON_BRL flag. No need to repeat this in braille_unregister_console().

    Drop the repetitive checks from Braille console driver.

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • 079c9534a   vt:tackle kbd_table ... Browse Code »
    43

    Keyboard struct lifetime is easy, but the locking is not and is completely
    ignored by the existing code. Tackle this one head on

    - Make the kbd_table private so we can run down all direct users
    - Hoick the relevant ioctl handlers into the keyboard layer
    - Lock them with the keyboard lock so they don't change mid keypress
    - Add helpers for things like console stop/start so we isolate the poking
    around properly
    - Tweak the braille console so it still builds

    There are a couple of FIXME locking cases left for ioctls that are so hideous
    they should be addressed in a later patch. After this patch the kbd_table is
    private and all the keyboard jiggery pokery is in one place.

    This update fixes speakup and also a memory leak in the original.

    This adds a minimalistic braille screen reader support. This is meant to
    be used by blind people e.g. on boot failures or when / cannot be mounted
    etc and thus the userland screen readers can not work.
