    Subject[git pull] drm patches for 2.6.27-rc1
    Hi Linus,

    This is a new tree, I had a conflict with your latest tree due to some
    trivial cleanups you merged. I've added the fix for CVE-2008-3831 which is
    unembargoed.

    Please pull the 'drm-next' branch from
    ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-next

    This contains two patches outside the DRM git tree to add exports for GEM
    functionality while we await Nick Piggins vmap and shmem changes.

    This update contains the following.

    1. CVE-2008-3831 - fixes for memset on arbitrary memory via i915 on G33 hw and
    above.
    2. Intel GEM memory manager .
    3. Opregion support for Intel Integrated chipsets.
    4. Updated radeon driver with support for new chipsets + bugfixes
    5. vblank reworking to save power and interrupts on intel/radeon GPUs.

    Dave.

    drm/i915: fix ioremap of a user address for non-root (CVE-2008-3831)

    Olaf Kirch noticed that the i915_set_status_page() function of the i915
    kernel driver calls ioremap with an address offset that is supplied by
    userspace via ioctl. The function zeroes the mapped memory via memset
    and tells the hardware about the address. Turns out that access to that
    ioctl is not restricted to root so users could probably exploit that to
    do nasty things. We haven't tried to write actual exploit code though.

    It only affects the Intel G33 series and newer.

    drm: Add GEM ("graphics execution manager") to i915 driver.

    GEM allows the creation of persistent buffer objects accessible by the
    graphics device through new ioctls for managing execution of commands on the
    device. The userland API is almost entirely driver-specific to ensure that
    any driver building on this model can easily map the interface to individual
    driver requirements.

    GEM is used by the 2d driver for managing its internal state allocations and
    will be used for pixmap storage to reduce memory consumption and enable
    zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable
    GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.

    GEM needs to create shmem files to back buffer objects. Though currently

    is running, for boot-time message display.

    drm: Rework vblank-wait handling to allow interrupt reduction.

    Previously, drivers supporting vblank interrupt waits would run the interrupt
    all the time, or all the time that any 3d client was running, preventing the
    CPU from sleeping for long when the system was otherwise idle. Now, interrupts
    are disabled any time that no client is waiting on a vblank event. The new
    method uses vblank counters on the chipsets when the interrupts are turned
    off, rather than counting interrupts, so that we can continue to present
    accurate vblank numbers.

    separate i915 suspend/resume functions into their own file

    [Patch against drm-next. Consider this a trial balloon for our new Linux
    development model.]

    This is a big chunk of code. Separating it out makes it easier to change
    without churn on the main i915_drv.c file (and there will be churn as we
    fix bugs and add things like kernel mode setting). Also makes it easier
    to share this file with BSD.

    Add Intel ACPI IGD OpRegion support

    This adds the support necessary for allowing ACPI backlight control to
    work on some newer Intel-based graphics systems. Tested on Thinkpad T61

    i915: Add support for MSI and interrupt mitigation.

    Previous attempts at interrupt mitigation had been foiled by i915_wait_irq's
    failure to update the sarea seqno value when the status page indicated that
    the seqno had already been passed. MSI support has been seen to cut CPU
    costs by up to 40% in some workloads by avoiding other expensive interrupt
    handlers for frequent graphics interrupts.

    SiS DRM: fix the memory allocator if the SIS FB is built as a module

    Fix the SIS DRM memory allocator if the SIS FB built as a module. The SIS DRM
    code initialises the mm allocation hooks, but _only_ if the SIS FB is not
    built as a module because it depends on CONFIG_FB_SIS, and that's unset if the
    SIS FB is not built in. It must check CONFIG_FB_SIS_MODULE as well.
