hi there,

sorry for the delay (busy time at work and first time doing a git
bisect).

Here is the final result of the bisection:

    drm/nv44/vm: fix and enable use of "real" pciegart

    Something seems to be missing in regards to flushing specific ranges of
    the TLB.  For the moment, flushing the entire thing seems to make it
    work alright.

    Should give 39-bit DMA addressing on the relevant chipsets.

    v2: allocate contig 16KiB for dummy pages, reported by mwk on irc
