  • 11bac8000   mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf ... Browse Code »

    ->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.

  • b3e3893e1   net: use core MTU range checking in misc drivers ... Browse Code »

    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

    hippi:
    - set min/max_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
    - remove redundant gprs_set_mtu

  • 3c13ab1d9   HSI: cmt_speech: Fix double spin_lock ... Browse Code »

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

    The bug was found using EBA (https://github.com/models-team/eba), which reported
    the following:

    Double lock
    first at drivers/hsi/clients/cmt_speech.c:443
    second at drivers/hsi/clients/cmt_speech.c:447
    In cs_hsi_read_on_control_complete defined at drivers/hsi/clients/cmt_speech.c:438:
    (!) drivers/hsi/clients/cmt_speech.c:443: spin_lock(& hi->lock);
    (?) drivers/hsi/clients/cmt_speech.c:445: msg->status == 4 -> true
    (!) drivers/hsi/clients/cmt_speech.c:447: cs_hsi_control_read_error(hi, msg);
    (!) drivers/hsi/clients/cmt_speech.c:407: __cs_hsi_error_pre(hi, msg, "control read",
    & hi->control_state);
    (!) drivers/hsi/clients/cmt_speech.c:382: spin_lock(& hi->lock);

  • 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.

  • 53c703501   HSI: omap-ssi: add COMMON_CLK dependency ... Browse Code »

    Enabling the omap ssi driver without COMMON_CLK results in a build failure:

    drivers/hsi/controllers/omap_ssi_core.c: In function 'ssi_clk_event':
    drivers/hsi/controllers/omap_ssi_core.c:304:7: error: 'PRE_RATE_CHANGE' undeclared (first use in this function)

    This adds a Kconfig dependency to avoid the invalid configuration.
