  • 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

    ->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to
    take a vma and vmf parameter when the vma already resides in vmf.

    Remove the vma parameter to simplify things.

    firewire-net:
    - set min/max_mtu
    - remove fwnet_change_mtu

    nes:
    - set max_mtu
    - clean up nes_netdev_change_mtu

    xpnet:
    - set min/max_mtu
    - remove xpnet_dev_change_mtu

    - remove hippi_change_mtu

    batman-adv:
    - set max_mtu
    - remove batadv_interface_change_mtu
    - initialization is a little async, not 100% certain that max_mtu is set
    in the optimal place, don't have hardware to test with

    rionet:
    - set min/max_mtu
    - remove rionet_change_mtu

    slip:
    - set min/max_mtu
    - streamline sl_change_mtu

    um/net_kern:
    - remove pointless ndo_change_mtu

    hsi/clients/ssi_protocol:
    - use core MTU range checking
    - remove now redundant ssip_pn_set_mtu

    ipoib:
    - set a default max MTU value
    - Note: ipoib's actual max MTU can vary, depending on if the device is in
    connected mode or not, so we'll just set the max_mtu value to the max
    possible, and let the ndo_change_mtu function continue to validate any new
    MTU change requests with checks for CM or not. Note that ipoib has no
    min_mtu set, and thus, the network core's mtu > 0 check is the only lower
    bounds here.

    mptlan:
    - use net core MTU range checking
    - remove now redundant mpt_lan_change_mtu

    fddi:
    - min_mtu = 21, max_mtu = 4470
    - remove now redundant fddi_change_mtu (including export)

    fjes:
    - min_mtu = 8192, max_mtu = 65536
    - The max_mtu value is actually one over IP_MAX_MTU here, but the idea is to
    get past the core net MTU range checks so fjes_change_mtu can validate a
    new MTU against what it supports (see fjes_support_mtu in fjes_hw.c)

    hsr:
    - min_mtu = 0 (calls ether_setup, max_mtu is 1500)

    f_phonet:
    - min_mtu = 6, max_mtu = 65541

    u_ether:
    - min_mtu = 14, max_mtu = 15412

    phonet/pep-gprs:
    - min_mtu = 576, max_mtu = 65530

    Release &hi->lock before calling `cs_hsi_control_read_error' to avoid deadlock.

    the following:

  • c2f90a465   HSI: omap-ssi: move omap_ssi_port_update_fclk ... Browse Code »

    After the clk change support, the ssi omap ssi core driver
    now calls into the port driver to change fclk. This function
    was previously inside of an #ifdef, because it was only used
    when CONFIG_PM is enabled. Now it also gets used without
    power management support:

    drivers/hsi/built-in.o: In function `ssi_clk_event':
    omap_ssi_port.c:(.text+0x1bf8): undefined reference to `omap_ssi_port_update_fclk'

    This moves the function outside of the CONFIG_PM guard.

  • ac8e3ff3a   HSI: omap-ssi: include pinctrl header files ... Browse Code »

    The driver now uses some pinctrl functions, but fails
    to build if PINCTRL is disabled because the respective
    header files are only included indirectly:

    drivers/hsi/controllers/omap_ssi_core.c: In function 'ssi_clk_event':
    drivers/hsi/controllers/omap_ssi_core.c:317:4: error: implicit declaration of function 'pinctrl_pm_select_idle_state' [-Werror=implicit-function-declaration]
    drivers/hsi/controllers/omap_ssi_core.c:339:4: error: implicit declaration of function 'pinctrl_pm_select_default_state' [-Werror=implicit-function-declaration]
    drivers/hsi/controllers/omap_ssi_port.c: In function 'ssi_flush':
    drivers/hsi/controllers/omap_ssi_port.c:520:2: error: implicit declaration of function 'pinctrl_pm_select_idle_state' [-Werror=implicit-function-declaration]

    This includes the headers from the files that call the functions,
    which works even if pinctrl is turned off.
