[patch 0/3] AHCI Link Power Management

Hi,
This series of patches enables Aggressive Link Power Management for AHCI 
devices, as documented in the AHCI spec.  On my laptop (a Lenovo X60), this
saves me a full watt of power.  On other systems, reported power savings
range from .5-1.5 Watts.  It has been tested by the kind folks at #powertop
with similar results.  Please give it a try and let me know what you think.

thanks,
Kristen
