  • 768ae309a   mm: replace get_user_pages() write/force parameters with gup_flags ... Browse Code »

    This removes the 'write' and 'force' from get_user_pages() and replaces
    them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers
    as use of this flag can result in surprising behaviour (and hence bugs)
    within the mm subsystem.

  • d4edcf0d5   mm/gup: Switch all callers of get_user_pages() to not pass tsk/mm ... Browse Code »

    We will soon modify the vanilla get_user_pages() so it can no
    longer be used on mm/tasks other than 'current/current->mm',
    which is by far the most common way it is called. For now,
    we allow the old-style calls, but warn when they are used.
    (implemented in previous patch)

    This patch switches all callers of:

    get_user_pages()
    get_user_pages_unlocked()
    get_user_pages_locked()

    to stop passing tsk/mm so they will no longer see the warnings.

    Pull powerpc update from Benjamin Herrenschmidt:
    "The main highlight is probably some base POWER8 support. There's more
    to come such as transactional memory support but that will wait for
    the next one.

    Overall it's pretty quiet, or rather I've been pretty poor at picking
    things up from patchwork and reviewing them this time around and Kumar
    no better on the FSL side it seems..."

  • 9655aa6b8   drivers/virt: the Freescale hypervisor driver doesn't need to check MSR[GS] ... Browse Code »

    The MSR[GS] bit indicates whether the kernel is running in processor guest
    state mode, but such a check is unnecessary. The driver already checks
    for the /hypervisor node and the fsl,hv-version property, so it already
    knows that it's running under the Freescale hypervisor.

    There is nothing in the driver that inherently requires guest state,
    anyway.

    This fixes a break that can occur in some randconfig builds.

  • 6db719940   drivers/virt: introduce Freescale hypervisor management driver ... Browse Code »

    Add the drivers/virt directory, which houses drivers that support
    virtualization environments, and add the Freescale hypervisor management
    driver.

    The Freescale hypervisor management driver provides several services to
    drivers and applications related to the Freescale hypervisor:

    1. An ioctl interface for querying and managing partitions

    2. A file interface to reading incoming doorbells

    3. An interrupt handler for shutting down the partition upon receiving the
    shutdown doorbell from a manager partition

    4. A kernel interface for receiving callbacks when a managed partition
    shuts down.
