The cmatest module that I use tries to allocate blocks from 4 KiB to 256
MiB (in increments of powers of two). With next-20120926 this always
fails at 8 MiB, independent of the CMA size setting (though I didn't
test setting the CMA size to <= 8 MiB, I assumed that would make the 8
MiB allocation fail anyway). Note that I had to apply the attached patch
which fixes a build failure on next-20120926. I believe that Mark Brown
posted a similar fix a few days ago. I'm also attaching a log from the
module's test run. There's also an interesting page allocation failure
at the very end of that log which I have not seen with next-20120925.

I've run the same tests on next-20120925 with the CMA size set to 256
MiB and only the 256 MiB allocation fails. This is normal since there
are other modules that already allocate smaller buffers from CMA, so a
whole 256 MiB won't be available.

Vanilla 3.6-rc6 shows the same behaviour as next-20120925. I will try
3.6-rc7 next since that's what next-20120926 is based on. If that
succeeds I'll try to bisect between 3.6-rc7 and next-20120926 to find
the culprit, but that will probably take some more time as I need to
apply at least one other commit on top to get the board to boot at all.

So this really isn't all that new, but I just wanted to confirm my
results from last week. We'll see if bisection shows up something
interesting.
