Having missed the ENOMEM return via i915_gem_fault(), there are probably
other paths that I also missed. By not enabling NORETRY by default these
paths can run the shrinker and take memory from the system (but not from
our own inactive lists because our shrinker can not run whilst we hold
the struct mutex) and this may allow the system to survive a little
whilst our drivers consume all available memory.

Roman, can you give this patch a spin?

Applied to 2.6.33-rc5, stress-test under heavy load, no problem so far. Looks fine!

Here it works too, thanks!
