I've put up a small updated -ck version for 2.6.37. There are only 2 changes: 1. The build fix for it not compiling with CPU HOTPLUG disabled, and 2. I've dropped the patch called mm-make_swappiness_really_mean_it.patch . This second patch broke a while back and I never noticed because I had swap disabled, sorry. It works better with it disabled. Note that the ubuntu packages I recently made available include this change which I quietly snuck in, but I will make ck2 packages officially available just to avoid confusion ;) If you've built your own 2.6.37-ck1 then I recommend upgrading only if you have swap enabled on your machine (which most people still do). Alternatively if you built it with CPU_HOTPLUG enabled just to make it build, then you _can_ upgrade to this version to build with it disabled but you won't notice a difference with the feature disabled - your kernel will only be slightly smaller. It might be a few nanoseconds faster..
