ASPM Patch has Landed on Stable Kernel

Greg has released a special edition of a stable kernel with only a single fix, which is to fix the power consumption for portable devices, such as laptops and netbooks. The patch is touching the ASPM (Active State Power Management) area and it was previously poorly implemented so that it consumes more power than it should be.

Matthew Garrett worked on this problem and he finally pushed his work into Linux Kernel 3.3 which is now on development and Greg wanted to prepare a special release of stable kernel that only has one patch to make it easier for user to spot any differences compared to previous release.

I think it's worthed to have this kernel available on -Current since it will make laptops/netbooks life longer since there is a decreament in power consumption.
