Here is a copy of the patch added to the md-accel series
(git://lost.foo-projects.org/~dwillia2/git/iop md-accel-linus). This
along with some other code re-factoring makes async_tx mimic the
organization of crypto, and should resolve the S390 clash.

async_tx: add the Kconfig infrastructure for async_tx
From: Dan Williams <[email protected]>
async_tx is similar to crypto in that there is an api component and a
drivers component.
* Add 'source "async_tx/Kconfig"' to the per architecture Kconfig files,
for each architecture that sources drivers/md/Kconfig (which appears
to be
all of them).
* Add 'select' statements for the subsystems that use async_tx
(md-raid4,5)
