    The conditionals were testing different values, but then all freeing the
    same one, which could result in a double free.

    A simplified version of the semantic match that finds this problem is as
    follows: (http://coccinelle.lip6.fr/)

    Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias
    is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable
    "macintosh" platform drivers, to re-enable auto loading.

  • d31e81718   [PATCH] powerpc: windfarm shall request it's sub modules ... Browse Code »

    The windfarm code, in it's current incarnation, uses request_module() to
    load the various submodules it needs for a given platform so that only
    the main platform control module needs to be modprobed. However, it was
    missing various bits. This fixes it. In the future, we'll use some
    hotplug mecanisms to try to get all of this auto-loaded on the platforms
    where it matters but that isn't ready yet.

  • 018a3d1db   [POWERPC] powermac: Constify & voidify get_property() ... Browse Code »

    Now that get_property() returns a void *, there's no need to cast its
    return value. Also, treat the return value as const, so we can
    constify get_property later.

    powermac platform & macintosh driver changes.

    Built for pmac32_defconfig, g5_defconfig

  • ac171c466   [PATCH] powerpc: Thermal control for dual core G5s ... Browse Code »

    This patch adds a windfarm module, windfarm_pm112, for the dual core G5s
    (both 2 and 4 core models), keeping the machine from getting into
    vacuum-cleaner mode ;) For proper credits, the patch was initially
    written by Paul Mackerras, and slightly reworked by me to add overtemp
    handling among others. The patch also removes the sysfs attributes from
    windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm
    core to automagically expose attributes for sensor & controls.

  • 75722d399   [PATCH] ppc64: Thermal control for SMU based machines ... Browse Code »

    This adds a new thermal control framework for PowerMac, along with the
    implementation for PowerMac8,1, PowerMac8,2 (iMac G5 rev 1 and 2), and
    PowerMac9,1 (latest single CPU desktop). In the future, I expect to move
    the older G5 thermal control to the new framework as well.
