Hi Linus !
Kumar sent me a handful of Freescale related fixes and I added
another regression fix to the pile.
Cheers,
Ben.

All SOC device error interrupts are muxed and delivered to the core as a single

errors have to register for the MPIC error interrupt as a shared interrupt.

Hello everyone,
This is my alternative (simpler) attempt at solving the problems reported
by Qiang Liu with the async_tx API and MD RAID hardware offload support
when using the Freescale DMA driver.
The bug is caused by this driver freeing descriptors before they have been

There are several places where descriptors are freed using identical

The use of spin_lock_irqsave() was a stronger locking mechanism than was
actually needed in many cases.
As the current code is written, spin_lock_bh() everywhere is sufficient.

The current fsldma driver does not support the async_tx API. This is due
to a bug: all descriptors are released when the hardware is finished
with them. The async_tx API requires that the ACK bit is set by software
before descriptors are freed.
This bug is easiest to reprod

These drivers set the DMA_INTERRUPT capability bit when requesting a DMA
controller channel. This was historical, and is no longer needed.
Recent changes to the drivers/dma/fsldma.c driver have removed support
for this flag. This makes the carma drivers unable to find a DMA
