Subject: [PATCH 0/2] DMAENGINE: generic slave, generic status

This patch set will enable generic functions for controlling
slave transfers, e.g. the ability to pause and resume transfers,
as well as the ability to read a wider status including not only
the current and last transfer cookie but also the residual
bytes left on a channel.

This was discussed by Dan and Guennadi some while back and now
I implemented it.

I did my best to read my own code over and over again so I
didn't break anything, but please review again.

I need help: does someone have a list of defconfigs I need to
compile to compile-check the entire DMA engine subsystem?
I guess I will need a number of cross compilers as well, this
is a bit hairy but will probably help out in future refactoring
as well if I can get them to fly.
