Hey Andy, thanks for testing!  Could you test another patch for me as well, to switch DMA Engine over to using an IDA instead of an IDR?  This should save 576 bytes on a normal setup.

The patch itself is here:
http://git.infradead.org/users/willy/linux-dax.git/commitdiff/a4f4e8554639b3fba9a62c07ad0e2423ea1f5f31

but it may be better just to test the head of this tree:

as I keep fixing bugs :-)
