   Now I'm getting spectacular oops in cppi_controller_start() due to invalid
instruction. That is fixed by my patch removing '__init' annotations from the 2
functions in cppi_dma.c that still have it. I'm waiting for you to merge it.

   Most probably those '__init' annotations were what was wrong. It's likely
that the memory remained intact in case of in-kernel glue layer but got already
spoiled in case of the modular glue layer...

   I meant "luckily" here, of course. :-)
