commit 0037ad4186c11267d85fcde378be79eb6acf74f3

    [intel] Remove broken mutex protection from dri_bufmgrs.
    
    Now that the dri_bufmgr is stored in the context rather than the screen, all
    access to one is single-threaded anyway.

    [intel] Enable INTEL_DEBUG=bufmgr output in TTM mode as well as classic.

commit 9f7d6b72108d9d8bec5f567bcaf33714ffe3ebc2

    [intel] assert that buffers are not mapped at last unreference.
    
    bufmgr_fake doesn't care about it, but with ttm we would end up with the
    buffer remaining referenced until application exit.
