Hi Rafael,
This patch has been Linux-ized so that you can take this and the SVKL patch. I was told that this was urgent for this merge window. Since they were simple, I thought it would be easier to have Sathya submit to Linux and ACPICA upstream separately. Going through this process made things a little more difficult so I'll be sure to communicate with you ahead of time if I do this again.
Erik
