[linux-audio-user] 2.6 which patches

I am compiling 2.6.11 and having trouble finding the patches I am supposed to use for low latency. In scouring the internet I find old references to a Realtime LSM, a Low Latency patch, and the Pre-emptable kernel patch. The later is included in the kernel now and I turned it on. The low-latency patch seems to only be findable as a patch to 2.4. The newest LSM is from a year ago. The user list website has a how to but it seems rather dated: http://www.djcj.org/LAU/guide/Low_latency-Mini-HOWTO.php3 Last update 2 years ago. What are the current set of patches you use and where are they? More importantly, how to you ready a CURRENT kernel for use with audio and where is the HOWTO on that? Thanks.
