Here's another minor update to this patch, now at version 6. Changes in 
this version are some code cleanups to the interrupt handler which 
should also provide a small performance gain.

---

This patch adds support for ADMA mode on NVIDIA nForce4 (CK804/MCP04) 
SATA controllers to the sata_nv driver. Benefits of ADMA mode include:

-NCQ support
-Reduced CPU overhead (controller DMAs command information from memory 
instead of them being pushed in by the CPU)
-Full 64-bit DMA support

ADMA mode is enabled by default in this version. To disable it, set the 
module parameter adma_enabled=0.
