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 chann

The use of spin_lock_irqsave() is a stronger locking mechanism than is
required throughout the driver. The minimum locking required should be
used instead. Interrupts will be turned off and context will be saved,

Hi all,
The following 8 patches enabling fsl-dma and talitos offload raid
operations for improving raid performance and balancing CPU load.
These patches include talitos, fsl-dma and carma module (caram uses
some features of fsl-dma).
Write performance will be improved by 25-30% tested by iozone

Sorry, I didn't make it clear. I did load acpihp_enum module first, and then
load acpihp_drv.

Various /proc/net files sometimes report crazy timer values, expressed
in clock_t units.
This happens when an expired timer delta (expires - jiffies) is passed
to jiffies_to_clock_t().
