Dmesg log - after third pass of piglit.

I was giving piglit a trial run, and noticed that there was a few errors about
the radeon driver being able to allocate gem objects.

Some piglit tests are about allocating as large textures as possible, which can
result in such intermittent allocation failures. It might be feasible to handle
this more gracefully in userspace, but otherwise it should be mostly harmless,
assuming there are no other, real problems associated with it.

AFAIK, allocation failures are correctly reported to applications as the
GL_OUT_OF_MEMORY errors.

--- Comment #5 from Christian König <deathsimple@vodafone.de> ---
Totally agree with that. Some piglit tests even allocate all the memory on
purpose to test that the driver can handle that gracefully, and the expectation
in the good case is that those error messages start to appear.

As long as you don't experience any crash, hang or something like this
everything should be fine.
