    Subject[ 016/102] parisc: agp/parisc-agp: allow binding of user memory to the AGP GART
    Date
    3.10-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Alex Ivanov <gnidorah@p0n4ik.tk>

    commit 06f0cce43a32bd2357cea1d8733bba48693d556b upstream.

    Allow binding of user memory to the AGP GART on systems with HP
    Quicksilver AGP bus. This resolves 'bind memory failed' error seen in
    dmesg:

    [29.365973] [TTM] AGP Bind memory failed.

    [29.367030] [drm] Forcing AGP to PCI mode

    The system doesn't more fail to bind the memory, and hence not falling
    back to the PCI mode (if other failures aren't detected).

    This is just a simple write down from the following patches:
    agp/amd-k7: Allow binding user memory to the AGP GART
    agp/hp-agp: Allow binding user memory to the AGP GART
