Description Dave Airlie 2009-09-30 22:36:04 UTC

Its possible that EXA can loop infinitely when we finishaccess causes a UTS which causes a sw fallback which causes a UTS etc.

    exa: avoid infinite loops if UTS sw fallbacks.
    
    The upload in finish access can cause an infinite loop if
    UTS returns FALSE in here.
