BTW, Ideally speaking the fix for AVR32 which will enable 32bit mem
support and enable BIG endian support should have been part of this
patchset. That code can go through DMA tree as these patches are
very closely related. Otherwise now you have to wait till these patches
are included in linux-next, then only you can send AVR32 patches for
inclusion.

So, maybe you can just add Acked-by from me and Arnd and include
AVR patches (Only changes related to these two patches) in the same series.
That will make life easier for you.
