Thank you, I think when I wrote my mail it wasn't pulled yet.

Ok, thank you.

AFAICT, the original one (97f8571e663c808ad2d01a396627235167291556) is
post-26, too.

Both should be applied together. Although it is unlikely that with the
broken patch MMC accesses will accidentally clear the DALGN bits of
other running (unaligned) DMA chains (I'm not aware of any drivers
using unaligned DMA), the PXA27x developer manual says that this "must
not" be done. If it would result in memory corruption or lockups, I
don't know.
